So, if I understand correctly: update to a 2.6.28 kernel first.  Then do I:

1.  use the i915.ko generated by the kernel compile?
or
2.  export OS_HAS_GEM=1, rebuild drm from git, use drm/linux-core/i915.ko?

(tried to export OS_HAS_GEM=1 and rebuild drm-git with my 2.6.27.4 
kernel; no good)

Thanks
