I get a similar Oops at boot; I noticed this warning during compilation:

drivers/char/drm/drm_agpsupport.c: In function `drm_agp_init':
drivers/char/drm/drm_agpsupport.c:391: warning: implicit declaration of function `agp_find_bridge'
drivers/char/drm/drm_agpsupport.c:391: warning: assignment makes pointer from integer without a cast

I dont know what header to include/modify to make it go away.
DRM and AGP are compiled into the kernel (no modules).
