Thanks for the acpidump.

Please verify that /proc/acpi/ac makes sense in both cases,
and that you get AC/DC events when you switch between AC and battery.

Please compare the contents of /proc/acpi/battery
in both cases.

Please test brightness control,
via either /proc/acpi/video or /sys/class/backlight
in both cases.

Also, please test hibernate to disk with both params,
and see if /proc/acpi/thermal_zone/* still make sense
before and after.

thanks,
