I did a small test this morning with ami-e4c9388d:

Originally running 2.6.37-11 and showing sda and sdb in /proc/partitions. I did a build from the current master-next in Natty:

This works with or without the xen_emul_unplug=unnecesarry switch (expected as m1.large is not HVM). So we seem to be ok with just reverting the patch. Though we should check whether we now need the argument for our cluster instances.
