Too bad, this implies that the AC module does not get reinitialized after
resume and I suspect that acpi core is broken on 2.6 in this regard.

I'll compile 2.6 and try it on my HW.

Perhaps the ACPI people could advise how to increase debug verbosity
to see what happens or if that can't be done, put some printks into AC
module to see what happens when the module is loaded on resume.
