can not use intel GPU, no /dev/dri/card0

[uki]

Hi,

I'm getting the folowing error when I try to start X using intel drivers:

[  8669.844] (II) Loading /usr/local/lib/xorg/modules/drivers/intel_drv.so
[  8669.844] (WW) VGA arbiter: cannot open kernel arbiter, no multi-card support
[  8669.844] drmOpenDevice: node name is /dev/dri/card0
[  8669.844] Failed to change owner or group for file /dev/dri! 2: No
such file or directory
[  8669.844] Failed to change owner or group for file /dev/dri/card0!
2: No such file or directory
[  8669.844] drmOpenDevice: open result is -1, (No such file or directory)

2: No such file or directory
[  8669.844] drmOpenDevice: open result is -1, (No such file or directory)
[  8669.844] drmOpenDevice: Open failed

I assume I overlooked something while configuring the system (I dual
boot stable and release, this is on stable, release works fine).
Please help.

my make.conf has:
WITH_NEW_XORG="YES"
WITH_KMS="YES"

my kernconf:
device          agp
device          dpms
options         X86BIOS

device          drm
device          i915drm
device          radeondrm
