This really has nothing to do with Sat-5.5, but we need this newer version of rhn-virtualization-host released before the rhel-5.9 client tools, and aligning it with the Sat-5.5 release was the easiest way to do that. There should be no change to behaviour for clients with this rpm update.
See bug 761489 for the change that requires this. Committed to Sat-5.5: 9231a402a62349269c1572d33c0069df7129e038 and 762640a67e19c69f0bc7dc2ec4e05e52ade8f504
