Randy,

        Thanks! pci-nomsi enabled me to boot. I'm able to get a domu up and 
login via vncviewer.
Networking isn't working however. I created xenbr0 with no IP address, as it was
previously. Something isn't correct. I don't see the interfaces that were part 
of the
bridge before:

   tap0
   vif1.0
   peth0
   vif0.0

I vaguely remember the xen scripts created those. I'll have to read up on it 
after a bit
of sleep. Thanks again.

Andy
