The kdrive infrastructure is small because X servers don't need to be
complicated to be useful.  What I'd like to do is move the X server to
depending more on common kernel infrastructure, like DRI or fbdev (except
fixed).  I think the kernel should support:

 1)	Device detection
 2)	Device arbitration
 3)	DMA/IRQ management
 4)	Video memory allocation
 5)	AGP memory allocation
 6)	Mode selection (maybe with user-mode help?)
 7)	Input devices (/dev/input + hotplug)

That way GL apps could talk directly to the hardware when appropriate, or 
share the system with X at other times.  I'd also like to look into 
ways to share surfaces across X and GL so that we can use GL to composite 
X window contents.

If you've got kernel support for EDID and other Radeon bits merged into 
the DRI, it would be fun to write a DRI-based Radeon kdrive server and see 
how fast we can make it go.
