What kernel version and .config? IIRC, non-kms is no longer supported (at least 
on linux)

I'm running 845G with kernel 2.6.33, xorg-server 1.7.5, and xorg-video-intel 
from git as of a few weeks ago, and while there are a few bugs, mostly things work.

For reference, I have
CONFIG_AGP=m
CONFIG_AGP_INTEL=m
CONFIG_DRM=m
CONFIG_DRM_I915=m
CONFIG_DRM_I915_KMS=y
CONFIG_VIDEO_OUTPUT_CONTROL=m
CONFIG_FB=m
..and various other options those autoselect, but everything else visible under 
the Device Drivers -> Graphics support menu is set to n.
