I thought about doing this too.  DRM gives us the ideal platform for it
because the command queue stuff is already in the kernel waiting to be
used - you just need to feed it the right commands (which can be copied
from the Xorg driver).  It certainly be nice to have (even though we
hopefully don't spend a lot of time showing the console), but I'm
suffering a lot for time at the moment. It'd be a great project for
someone who wants to learn a bit about Glamo (or graphics acceleration
in general) - no low-level scariness or NDA required, I promise...
