[Fedora-xen] 2.6.31-1.2.65.xendom0.fc12.x86_64 crash on boot

[Charles Gruener]

This absolutely fixes my issue.  With the latest patch, I can boot my  
system successfully if NX is enabled or disabled in the BIOS.

Just a final note, I do need to make sure VT-d is disabled in the  
BIOS, and then I can boot.  This was obviously not addressed in this  
patch nor was it requested to be.  It would be nice to have it working  
at some point as this machine will hopefully have a bunch of NVidia  
cards in it that will need to be dedicated to each of the domU's for  
CUDA research.

Thank you all for your prompt and courteous responses.  It makes me  
proud to be a RHCE when I get support from a community of developers  
like you guys.
