No battery status with 2.6.24-rcX anymore

[Jan Willies <jan@willies.info>]

Hello,

Since the 2.6.24-rcs my ACPI doesn't work correctly anymore. For instance, battery level is not reported and wakeup from S3 (s2ram) doesn't work anymore. My laptop is a Medion MD 96400 (MSI S270 equivalent).

My menuconfig looks like this:

[ ]   Deprecated /proc/acpi files
[ ]   Deprecated power /proc/acpi folders
[ ]   Deprecated /proc/acpi/event support
<M>   AC Adapter
<M>   Battery

--- Power supply class support
[ ]   Power supply debug
< >   Generic PDA/phone power driver
< >   DS2760 battery driver (HP iPAQ & others)

I have to boot with 'nolapic' to not run into a 10000+ wakeup/s issue but those notes above were made without 'nolapic'.
