I'm not sure it matters, but I'm testing against a changeset about a week old:
http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=1c4a5b37b55c56e49135e65728137f54288d1fe6

Plus patches specific to XenClient Enterprise.

The end result is this is a nice set of patches where there is only
_one_ change in the x86 code (and it is just more of dealing with
error case) - and the rest are all done in Xen side.

I'm sorry to report that this series doesn't seem to work in my setup
against xen-unstable.

To verify that it was, in fact this patch series, and not another Xen
regression - I swapped out the kernel with this patch series, with an
identical one, replacing only this series with your acpi-s3.v9 branch
- and everything worked fine.

Thanks for testing it!

I had tested it with Xen 4.1.3, which could be doing something different.
Will see what is up.
