You're starting > to sound like those old KGI people, with their 'safe kernel > drivers for video' spiel... ;^) There are actually distinct similarities between some DRI drivers and what Linus suggested the KGI people needed to be doing. Certain hardware isnt totally user safe (not on the extremes of the voodoo1 here) and the drivers do small amounts of work to stop abuse. All mode changes, rendering primitives and the like are however in userspace. I firmly believe you can do X11 with 3D in windows, including partial occlusion of 3d windows on a 3dfx voodoo1 or voodoo2 card. Alan
