Hi all,
I had a Radeon 64MB OEM for testing with Maya3 under Win2K, and the problems I came across weren't exactly minor.
The two earlier driver revisions randomly corrupted the windows desktop and caused BSODs.
The latest 3043 driver didn't corrupt the desktop anymore, but it still causes BSODs if you run Maya in very high resolutions (1900*1080 etc.)
Even in lower resolutions, using the shaded mode is quite an experience, since the basic grey lambert is switching colors on screen at will, sometimes turning green, blue, yellow etc. The same happens even with textured models, their colors get corrupted.
Using paint effects brushes leave trails on screen, and the brush itself is grey instead of red ( oh, the tragedy! 
All vertices and cvs are displayed as single pixels, which makes picking them extremely hard.
Also the Radeon has a texture handling problem. If you load the card's local memory full of 32-bit textures, your system locks up so it needs a hard reset. Switching the "force 32bit textures to 16bit" option on in the driver OpenGL settings alleviates this problem.
On the hardware side the card caused wavering on the screen, which was helped in my case by reversing h-sync. Several Sony trinitron-tube -users haven't been as lucky. Check the longest running thread on www.rage3d.com radeon forums for details.
Also the geometry performance on the radeon is surprisingly slow for the numbers advertised. Simple opengl geometry tests showed the radeon to be half as fast as a Gloria II, and this was reflected in the performance in maya, when rotating models on screen. It could be that TL just isn't enabled in the Win2K drivers.
Just to be sure that it wasn't my hardware causing the problems, I tested the same card on a different workstation altogether, which had a clean install of Win2K, and none of the same hardware. The same problems were displayed.
On the bright side, I really liked the Radeon's 2D signal clarity, which was crisp even at the highest 1900*1200 resolution.
I am hopeful that the drivers will get better, and seeing an ATI engineer on this forum is positive news indeed. If ATI won't cripple the Radeon and sell a professional version at triple the price, like some other competitors, they have a great chance of providing a cheap but very capable card for Maya.
