I am busy getting the GPL version of our DDK out the door, but will soon 
be back onto the OpenGL in SNAP project and would hope we can get an 
Xserver driver going based on SNAP soon. Then it will be real easy to 
make it work using OpenGL too.

It should not take that much code - this is probably just code bloat. The 
SciTech SNAP driver for the ATI Radeon family supports all Radeon 
chipsets and includes full 2D acceleration code and is only 140K. Still, 
supporting all the combinations you need to support for a full fledged 
driver does take up space. A stripped down Radeon driver that just did 
basic mode sets could probably live in a 20K module, but then it would 
have a pretty limited feature set and no hardware acceleration ;-)
