ACPI on Compaq nx6125 not updating battery state

I'm running Gentoo Linux on a nx6125 and got most things working. The last big problem is, that the battery state (/proc/acpi/battery/C175/state) doesn't update after the system runs for a while.

The strange thing: when I read the cpu-temperature from /proc/acpi/thermal_zone/TZ1/temperature the battery state updates. There is 100% cpu usage for about 2 seconds after doing so. The bad thing: it seems like the fans don't run until cat'ing/reading from this file, even if the temperature reaches a trip point defined the thermal zone.

It seems like the battery state stops updating after the temperature reaches the trip point, but I'm not sure about that.

I tryed booting with ec_burst=1, but it's still the same.

I hope you can help me :)

Seen some ACPI issues on these laptops (for example

Its an 64bit Turion system so guess it'll take some time to adapt (kernel and ACPI module) to use ACPI smoothly.Check also this (kernel patch?) :
