>Description:
Xorg (from pkgsrc) needed dri to work, DRI needed drm support in i915 kernel 
driver for the Mobile GM45 chipset.
The patch is just adding the pci ids to the right place, more patches might be 
necessary for a full drm support (currently checking against the freebsd 
driver..)

after patching:
i915drm0 at vga0: Mobile Intel GM45 Express Chipset (unit 0)
i915drm0: AGP at 0xd0000000 256MB
i915drm0: Initialized i915 1.5.0 20060119

>How-To-Repeat:
install Xorg from pkgsrc and enable kernel agp, kernel drm and Xorg DRI when 
having a Mobile GM45 chipset.
>Fix:
trivial patch..:
