Looking briefly at the fc18 rpms, it appears that seabios is included
into the hvmloader binary.  If so, I doubt it would matter to the
distros as then it's already a separate copy (embedded within
hvmloader).

BTW, does Xen implement the "fw_cfg" interface to pass config info
(eg, bootorder) to SeaBIOS?
