>Description:
X -configure correctly identifies my video card but it doesn't seem to work with DRI and Accel enabled (default behavior). Also says "mtrr set failed: Device busy"

Logs (bit long to paste?):
- dmesg: http://sogub.com/nbsd-intel-x-issue-current/dmesg.txt
- xorg.conf.new (generated by X -configure): http://sogub.com/nbsd-intel-x-issue-current/xorg.conf.new
- xorg.conf.new diff from what changes were made to make X work: http://sogub.com/nbsd-intel-x-issue-current/working_vs_not_working-xorg_conf_new.diff
- xorg log: http://sogub.com/nbsd-intel-x-issue-current/xorg.log


>How-To-Repeat:
X -configure with the same driver/card/netbook? 
>Fix:
Set these options in x.org.new generated config, in the video card section:
Option     "DRI" "False" 
Option     "NoAccel" "True"
