there seems to be some problems with the battery interface on the macbooks

one is that sometimes /proc/acpi/battery/BAT0/* will only show 0-values,
which then can usually be cured by booting into MacOS and then rebooting
into linux. However I have no clear pattern when this happens, not every
cold boot can show this behaviour.

the more serious one is, that whenever the battery module is loaded,
I'm seeing lots of acpi interrupts, so that even on the idle machine
the cpu is kept busy.

powertop shows:
> Top causes for wakeups:
>   60.7% (1218.9)       <interrupt> : acpi


I'll attach acpidump and a dmesg with acpi debug output, please ask
for any other info needed to help ...
