f9 dell precision 490 X crashing nv vesa quadro FX 3500

[Skunk Worx]

Hi,

I have a Dell Precision 490 with a nvidia Quadro FX 3500 card installed.

Both the vesa and nv drivers crash the machine.

It is a little odd in that if I go into run level 3, then 'startx', X 
runs as expected...one time.

However any attempt to go into runlevel 5, or startx again 
(ctrl-alt-backspace and startx) from run level 3, results in a corrupt 
gui and a hard crash within seconds.

I have the hardinfo_report.html for the machine, Xorg.0.log for the nv 
success, Xorg.0.log for nv failure, Xorg.0.log for vesa failure, and the 
nv xorg.conf.

Is this sufficient info for a bugzilla? And does this sound better as 
one report against an X11 component or separate reports against the nv 
and vesa drivers?

Thanks,
John

PS : at no time was any proprietary driver installed on this machine.
