Hi Robert,

Same deal I'm afraid. I'll try and provide as much information about the 
hardware as I can (info taken after i915_drv.c was modified)

 From dmesg:
-----------------

[alex at laptop /usr/home/alex]$ dmesg |grep agp
agp0: <Intel 82855GME (855GME GMCH) SVGA controller> on vgapci0
agp0: detected 892k stolen memory
agp0: aperture size is 128M

[alex at laptop /usr/home/alex]$ dmesg |grep drm
drm0: <Intel i852GM/i855GM GMCH> on vgapci0
info: [drm] AGP at 0xf0000000 128MB
info: [drm] Initialized i915 1.5.0 20060119
drm1: <Intel i852GM/i855GM GMCH> on vgapci1

===========================

Could the problem be the agpgart?
