Bug#362431: upgrade broke X server

[Ken Foskey <foskey@optushome.com.au>]

I upgraded tonight and the xorg server broke.  Complaining about missing
bitmap and pcidata modules.

As outlined I commented out the offending line:

#  ModulePath "/usr/X11R6/lib/modules"

gdm and X now work successfully.

Problem: This particular line should have automatically been removed for
me by the upgrade process.

Thanks
Ken
