The thing he reported 2 weeks ago is a straightforward recursive dependency 
bug in the config entries:

  drivers/gpu/drm/Kconfig:8:error: found recursive dependency:
   DRM -> <choice> -> DRM_I915 -> FB -> FB_I810 -> AGP -> DRM

this is the precise circular dependency problem that the I810_FB and 
INTEL_FB changes in my patch solve.

Give my patch a try :-)
