Linux on PowerPC FAQ-O-Matic : X Windows :
Why can I only start X as root?
X needs to be run with root privileges to access the graphics
hardware. You need to turn on the setuid bit on the X server
program to allow normal users to run X. To do this, type
the following as root:
cd /usr/bin/X11
chmod 4511 Xpmac-6.3
You may need to change Xpmac-6.3 to Xpmac-6.1 or Xmklinux
depending on how old your X server is (Xpmac-6.3 is the most
current one; it is based on the latest release of X).
For more information on file ownership, look at any introductory
Unix book or read the man page for chmod(1).

"Actually your XF68_FBDev should *not* be setuid. This has thepotential to create some security problems, which may or may not be an issue depending on how your system is used. Use of a setuid server was phased out with the introduction of 3.3.2. There is more info on this subject at http://www.xfree.org/FAQ/#Xwrapper
"You should have a binary named Xwrapper(in /usr/X11R6/bin) that is setuid."
Sure enough, with Xwrapper setuid and XF68_FBDev not, it allows non-root users to startx. Yay!
