finalized documentation for driver release (as V0.41). All my cards confirmed OK and very fast compared to 'the old days'. 

It's confirmed BTW that GeForce PCIe/AGP 6600GT is working OK (tested on 3 cards), and also GeForce AGP 6800GT is OK (one card tested).

<li>If you have trouble using AGP mode, you should prefer tweaking the AGP busmanager settings file as it might well enable you to use a 'lesser' AGP mode instead of falling back to PCI mode alltogether.

<li><strong>dma_acc:</strong><br>
You can select one of two methods for (2D) acceleration here: PIO mode and DMA mode. DMA mode works 2-3 times as fast as PIO mode on modern CPU's (beyond 2Ghz or so), and should still match the PIO mode speed on slower CPU's (below 500Mhz).
You can select one of two methods for (2D) acceleration here: PIO mode and DMA mode. DMA mode works 4-10 times as fast as PIO mode on modern CPU's (beyond 2Ghz or so), and should still be 2-3 times as fast as PIO mode on slower CPU's (below 500Mhz).
<ul>
<li><strong>false:</strong><br>
If the default setting does not work as expected, you can try falling back to PIO mode acceleration. Note however that PIO mode is currently not working on NV40 and higher GPU's (GeForce 6200, 6600 and 6800 like types). Also, chances are that this method of acceleration will be removed in future driverversions (so be sure to let me know if you are having trouble with DMA mode!).

<ul>
<li>Added new acceleration method using DMA command fetching. You can now choose beween (the old) PIO mode and (the new) DMA mode acceleration via a new switch in nv.settings (DMA mode is now the default). DMA acceleration is say 2-3 times as fast as PIO mode acceleration on systems with relative fast CPU's (above 2Ghz or so). On relative slow CPU's (500Mhz or lower) there is no speedgain left and both methods match about up.<br>
<strong>Note please:</strong> On NV40 and higher only DMA mode acceleration currently works;
<li>Execution of acceleration commands (DMA mode) has been optimized (compared to PIO mode): now the top-level acceleration functions are incorporated in the engine, and the engine's command execution itself is also optimized. This further increases DMA mode acceleration with upto a factor of 2, independant of CPU speed;

This further increases DMA mode acceleration with upto a factor of 2-3, independant of CPU speed;
<li>Execution of acceleration commands (PIO mode) is re-setup. Now it should be possible to use more engine commands than there are FIFO channels for them, by doing on-the-fly reconfiguring (DMA mode can do this also). This should be especially usefull when 3D acceleration is going to be setup later on;
<li>Added recognition for 20 new cards: Most GeForce 6200, 6600 and 6800 types are now recognized, and some more other cards as well;
<li>Modified cursor to be hardware synchronized to the screen's vertical retrace. This fixes the high CPU load on moving the mouse especially while being on the bottom of the screen (all GeForce series cards);
<li>Added DPMS support for digital flatpanels connected via DVI;
<li>Updated 'extended PLL' VCO limits: this (could) fix PLL locking trouble (shivering image / too low refreshrate) on NV31 (FX 5600), NV36 (FX/PCX 57xx) and NV40 and up (FX/PCX 6200, 6600 and 6800). Confirmed NV36, on a PCX 5750 for PCIe.

<li>Overlay fix for GeForce2 and GeForce4 MX Integrated GPU boards: updated RAM amount detection. The last 64Kb RAM is used for the card's BIOS or something so it's not available to the graphicsdriver;
<li>Enabled coldstart switch setting (called 'usebios' in nv.settings) in drivercode. Changed the default setting to keep the driver working in the same way it did before;

<li>Card coldstarts should now be operational (if enabled in nv.settings) on most cards, except TNT1, GeForce 6600 and GeForce 6800. Tested successfully on TNT2/TNT2-M64 (NV05), GeForce2 MX400 (NV11), GeForce4 MX440 (NV18), GeForce4 Ti4200 (NV28) and GeForce FX5200 (NV34). Note however that laptop panels and DVI panels will not work via coldstarting yet!
<li>The 'bandwidth trouble' existing on older cards, especially on some GeForce2 types, should be fixed now if you enable card coldstarting for these cards. Note that this problem existed because of a fault in these card's BIOSes (they missed some specific register programming). Confirmed a NV15 working OK now.

<li>Added AGP mode capability on AGP cards along with the option to block it in nv.settings. No GART and AGP aperture support; but if your card and system AGP host bridge support the 'fastwrite' (FW) feature, you'll notice a nice speedup of unaccelerated graphics.
