Problem with new DRI/DRM support for Intel 855GM

Hello,

I just discovered that the DRM drivers have been updated and my 855GM
is now supported by i915.ko.

If I load the module, the driver attaches:
drmsub1: <Intel i852GM/i855GM GMCH> mem 0xe8000000-0xefffffff,0xfaf00000-0xfaf7ffff at device 2.1 on pci0
info: [drm] AGP at 0xf0000000 128MB
info: [drm] Initialized i915 1.2.0 20041217

But when I start X.org (xorg-server-6.8.99.903), it says:
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (No such file or directory)
drmOpenDevice: open result is -1, (No such file or directory)
drmOpenDevice: Open failed
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (No such file or directory)
drmOpenDevice: open result is -1, (No such file or directory)
drmOpenDevice: Open failed

The problem is easily spotted, as there is only /dev/dri/card1. If I
try to symlink card1 to card0, the kernel says:
error: [drm:pid890:drm_unlock] *ERROR* Process 890 using kernel context 0

(PID 890 is the X server.)

while the X.org log file reports:
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 7, (OK)
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 7, (OK)
drmOpenByBusid: Searching for BusID pci:0000:00:02.0

drmOpenByBusid: drmGetBusid reports pci:0000:61:00.0
drmOpenDevice: node name is /dev/dri/card1
drmOpenDevice: open result is 7, (OK)
drmOpenByBusid: drmOpenMinor returns 7
drmOpenByBusid: drmGetBusid reports pci:0000:61:00.0

But anyway: It's very nice to see that 3D acceleration is going to
work Real Soon Now(tm) on my laptop. :-)
