AFAIK all open drivers for Linux 3D accel use DRI.

No, it obviously is, as an actually accelerated setup worked decently.
Xorg doesn't help on my i82855GM laptop or nVidia cards. Also my Millennium
G200s don't do 3D under NetBSD. I've had all of these work well with
either DRI or proprietary drivers under Linux.

Yes, most any card as recent as 2-3 years ago should work, but not under
