Twice now over the past year, I've had something edit the /etc/X11/xorg.conf 
file without user intervention.
The machine in question is a 3 headed X-Terminal that displays the accelerator 
control system application for a medical proton accelerator, and operated by 
staff who do NOT have root or root like access (sudo) on the X-Term, as once 
it's configured, it should never need changing. It lives on a private network 
(Network? Actually a crossover cable to the Sun box in a protected environment) 
with no reachable route even from within the organization.

Out of the blue, on 2 occasions now, an entry for 1 of the video cards (out of 
3) has changed it's driver entry from "nvidia" to "nv". This, of course, 
prevents X from starting.

This morning, while of the phone with the field service tech, I corrected the 
entry, set the xorg.conf file to 444, and when they rebooted the X-Term, it 
again changed the entry from "nvidia" to "nv".

Again, I corrected the xorg.conf file, reset it to 444, and rebooted the X-Term 
again, and it started fine, no changes.

This box does get rebooted quite frequently, yet the unexpected change has only 
happened 3 time total, once 6 months and probably 30+ reboots ago, and again 
twice this morning on back to back reboots. (Yet the third and forth reboots 
did NOT change the file)

I've never seen this happen before, and am at a bit of a loss wondering where 
to look.

CentOS 5.3, 2.6.18-128.1.6.el5 #1
The X-Term is diskless, boots via PXE from a Solaris 10 box. Diskless boot 
configured using stock Cent tools (system-config-diskless and friends)

Any suggestion where to look would be appreciated.

Thanks!
