+<ul>
+<li>Added recognition for one more card: a GeForce 6200 AGP (ID 0x0221);
+<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);
+<li>Concurrent overlay and 3D acceleration are now possible, although it's not perfect yet: you need to first start the 3D app, and later on the overlay app. This remaining problem will be fixed later on (hopefully).
+</ul>
