How are you starting xfce4?What's your .xinitrc look like?
Figured it was, wikipedia said it was IA32, so maybe we need to make it i686 so there's no question.
It just came up...uxa and sna are their respective acceleration methods.
Chrooting is probably what you're looking for.
If you have a broadfailure card, you will probably need broadcom-wl-pf-core2.
It's probably just drm.You might want to add intel_agp or i915 or drm_kms_helper to MODULES in /etc/mkinitcpio.conf
The line in .xinitrc needs to be exec ck-launch-session gnome-session
Does your user have access to the optical group?
Have you restarted nfsd?
You might use smartmontools to check to see that the drive(s) aren't failing.
