drm on i965M. Possible workaround.

[Andrey]

Hi, Alexandr!

I've tried your workaround. And it looks like it works (on my laptop HP 
Compaq 6710b with integrated Intel X3100 Graphic Card (GM965)).

# dmesg | egrep -i 'agp|drm'
agp0: <Intel GM965 SVGA controller> on vgapci0
agp0: detected 7676k stolen memory
agp0: aperture size is 256M
drm0: <Intel i965M> on vgapci0
info: [drm] AGP at 0xd0000000 256MB
info: [drm] Initialized i915 1.5.0 20060119
drm0: [ITHREAD]


BTW:

If there are no following devices statically compiled with the kernel:

device          drm
device          i915drm

then it seems that it is faster to test your workaround by means of:
# cp /usr/src/sys/dev/drm/drm_pciids.h 
/usr/src/sys/dev/drm/drm_pciids.h.orig
# cd /usr/src/sys/modules/drm/drm/
# make clean
# make depend && make obj && make && make install && make clean

Andrey
