Comment 15 for bug 898112

Looking over the patches, the infrastructural changes are quite limited. So the biggest hunk of change is the new driver. At least that helps in the argument in the sense that only Xen hosts/guests are affected. Still there are some things I think should be checked.
The new driver gets loaded in dom0 and pushes things into the hypervisor. What Xen version does this require for the hypervisor?
From the top of my head I am not sure whether there is a requirement/dependency for domU as well. But I think those probably get different acpi tables coming from xen. But at least it should be verified to boot older and newer guests.
