[Fedora-xen] Xen Crash at Boot on Dell PE 830 Running FC 5

Greetings,

I'm having some trouble getting my new workstation, a Dell PE 830, up and
running Xen on Fedora Core 5.   The last step I see in the boot process is
udev which completes with the standard [OK], then my monitor turns blank and
looses any signal from my machine.  If necessary, I could connect a serial
port to get additional info on exactly where it is crashing.

I'm using this machine as my desktop so I'd like to run X in the dom0 if
possible. Please let me know if doing so is considered poor form with Xen.

I've gone through the install process on an older Dell workstation
successfully following the Fedora Xen Quickstart FC 5 guide here:

http://fedoraproject.org/wiki/FedoraXenQuickstartFC5

The only way I've been able to work around this issue is to edit my
/etc/inittab and set the default run level to 3 in which case the machine
comes up clean.

I've verified that selinux is disabled as I've seen some info to the effect
that selinux and the nvidia drivers may have some issue.

I'm hoping I can pass some argument at boot time to make this work or
otherwise tweak something in the bios to get the xen kernel to boot and
support X.

Thanks in advance for any hints or tips.
