Thanks!

A little.  I've been using it on my HP nx6325 for some days with no visible
problems.

Well, I think the patches need to be modified to handle the case of devices
that can wake up both through PME# and the ACPI-based mechanism.
Also, I need to make ACPI enable the wake-up GPEs for PCI devices that are
supposed to be handled by it.

For this reasons I'm not sure they will be sufficiently tested before the
2.6.27 merge window.  Perhaps it's better to target the patchset at 2.6.28 and
make sure it gets some serious testing during the .27 cycle.

Thanks,
Rafael
