Ok, the CVS logs were confusing me here - the hypervisor is on 11540,
but the actual kernel is on 11740 - as Guillaume correctly points out
in his BZ ticket. Since 11740 is only 30 changesets before the 3.0.3
release tar.gz, and those 30 changesets contain some pretty important
bugfixes I plan to just sync the userspace xen RPM upto 3.0.3 official
tar.gz. This should give FC5 a fully operational Xen stack again.
