This patch series versus linux-next 2011/06/08 fixes various bugs including a nasty pinning bug found by Andre Bartke.
With these patches applied the driver passes the various GEM tests and you can use the KMS tools and test sets to set modes and display stuff from GEM buffers including those mapped from main memory via the GTT.
You can't yet take a GEM handle of the system frame buffer. That requires a trivial patch to drm_gem and a similar trivial patch to this driver.
The two main remaining tasks now are to provide a 2D command interface for the X server including support for blitting between GEM objects (so we need relocs) and to clean the code up.
Vblank support is also possible but doesn't seem terribly useful. ---
