Based on a quick scrobble through the CentOS 5.6 SRPMs it looks like a 3.1.0 hypervisor with a bunch of extra patches, but not this one. This is very likely the cause of the crash in mem_cgroup_create(), and probably the corruptions too. That would explain why they didn't happen on a 4.0.x SLES11 Xen, but not really why the original patch in this thread made it go away.
