<p><h2>Changes done for each driverversion:</h2></p>
<p><h1>head (Rudolf, svn 0.49)</h1></p>
<p><h1>nv_driver 0.50 (Rudolf)</h1></p>
<ul>
<li>Added recognition for one more card: a GeForce 6200 AGP (ID 0x0221);
<li>Added recognition for 10-15 more newer cards: mostly GeForce 6200, 6600 and 6800 types;
<li>Added 3D initialisation and updated 2D/3D command setup (defines and hash) for DMA acceleration (pre-NV40 only, 3D confirmed functional on TNT1 upto/including GeForce2Ti and GeForce4MX types: MX440 and MX4000 confirmed);
<li>Moved the DMA command buffer from graphics memory to main system memory, plus expanded it's size from 32kB to 1Mb. Buffer is mapped using MTRR-WC where available (confirmed speedups for both modifications; pre-NV40 only). Note that all TNT1 cards will be much faster with DMA acceleration now: the new mode is officially working on them, while the old mode used a 'nasty' workaround;
<li>Graphics engine is now using AGP transfers for fetching commands from the DMA buffer where available. Note that direct memory accesses are used: GART and AGP aperture are not in use. (confirmed speedup for this modification);
