xen-4.2.0 added a second qemu-xen image - the patch takes it out again. As 
the traditional qemu-xen was still the default so it didn't seem worth 
adding another, particularly as I would ideally like to drop xen's qemu 
altogether and go back to Fedora's.

As this seems to be about seabios, you should note that Fedora xen 4.2 
doesn't build its own seabios either, it uses the Fedora version - see the 
xen.use.fedora.seabios.patch patch. I didn't see any reason to duplicate 
what was already in Fedora (and as far as I understand it it is in general 
against Fedora's policy to do so).
