    Thanks for the tip; now it works. And besides I installed acpid - pretty
    cool to get a clean shutdown when the power-button is pressed :-)

    Eek, so my BIOS was right after all :-) The system is 63C at high load
    and 45C with the disconnection patch and ACPI enabled. With normal APM
    and no disconnection it is around 60C.

    Thanks anyway.
