I see updated xen packages in
http://ftp.scientificlinux.org/linux/scientific/5rolling/x86_64/SL/

The x86_64 versions (I haven't checked the i386 versions)
have no gpg signature.

I know that 5rolling is still a little unsteady, should I
hold off from frequent updates on my 54 test machine ?

Thanks,
