Not yet, I believe.

DRI is a 3D-on-XFree86 thing.

It could be done to add ioctl to allow app access to fb_fillrect
and fb_copyarea, and maybe fb_imageblit. But I'm not sure it could
make it to the Linux tree...

Yet it might worth talking about it. Stuff like microwindows
could probably use it.

It would be a simple ioctl wrapper around the fb_* stuff,
as those are mandatory (either HW-accel or using the supplied
generic functions).
