Hi all,

(please Cc, and sorry, don't know where to cross post that one)

switching from 2.6.28-rc9 to 2.6.29-rc1 my /dev/dri/* entries got lost.
Hardware is intel GM45:
[ 1.225368] agpgart-intel 0000:00:00.0: Intel Mobile Intel® GM45 Express Chipset
[ 1.230650] agpgart-intel 0000:00:00.0: detected 65532K stolen memory
[ 1.239716] PM: Adding info for No Bus:agpgart
[ 1.239844] agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xd0000000
[ 1.240093] PM: Adding info for No Bus:tpm0
[ 1.564241] [drm] Initialized drm 1.1.0 20060810

but X tells me:
(II) intel(0): Kernel reported 1264128 total, 1 used
(II) intel(0): I830CheckAvailableMemory: 5056508 kB available
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: Open failed
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: Open failed
[drm] failed to load kernel module "i915"

...

I see the post
[PATCH] drm/i915: why does kconfig hate?
but using that patch I still get:
drivers/gpu/drm/Kconfig:8:error: found recursive dependency: DRM
-> <choice> -> DRM_I915 -> FB -> FB_I810 -> AGP -> DRM

Any chance to fix that, or some suggestion?

Best wishes

Norbert
