The 2.6.20...xen kernel really is based off the 2.6.20 standard (Fedora) 
kernel.  So if the driver works in 2.6.20-2925 and not in the xen 
version, it's not because of a bugfix, but because of something else 
about Xen itself.

Very hard to say without seeing the messages.  Assuming that the boot 
isn't getting you into a shell, setting up a serial console is the 
easiest way to capture them.  Alternately you can try taking a 
screenshot with a digital camera.
