Geode cannot be used with GNOME because it requires root priviledges

Recent GNOME releases have switched to launching X as a non-root user.
This fails on Geode beause Geode tries to access the following devices, all typically owned by root:
$ ls -al /dev/dri/card0 /dev/fb0 /dev/cpu/0/msr ls: cannot access /dev/dri/card0: No such file or directory crw------- 1 root root 202, 0 Oct 19 23:06 /dev/cpu/0/msr crw-rw---- 1 root video 29, 0 Oct 19 23:06 /dev/fb0
On Debian (and some other distributions) the Geode driver hereafter requires the xserver-xorg-legacy wrapper to successfully launch with GDM-3. Other display managers that launch X as root still work as expected.
