I'm not sure whether I fully understand "pass-through" mode and
"non pass-through" mode. I guess "pass-through" mode means
exposing real battery to HVM, while "non pass-through" mode
contructs a virtual battery (as in your current patch) and then let
another xen specific daemon to convert virtual battery ops into
real ones. If I understand correctly, your current implementation
only targets for "non pass-through" mode. Then do you plan to
support the other, which is more difficult as you may need merge
part of real ACPI table with virtual ones...

Thanks,
Kevin
