Pretty stright forward. The pciback stuff isn't necessary, since fedora builds 
it as a module (not that 3.0.0 has a pciback, anyway) - it's just 
documentation to remind me how it is done. With f15's 2.6.38, I had to add '3' 
to the end of the 'vmlinuz' line in the xen stanza. You might try that, just 
to see if you can get a text login. (And there is always 'nomodeset' to try.)

Since 3.0.0 doesn't have the vga text patch, the screen will go briefly blank 
between the xen hypervisor output, and when drm kicks in the kernel output.
