For me it works. I just echo'ed "3" into /proc/acpi/fan/FN02/state and 
it stopped. The thermal zone 0 is the (corresponding) CPU (would have 
expected 2...).

No need - the trip point is around 90 degees for the CPU... Right now, i 
generate a lot of load, but it took me more than 30 to get there.

Note: The acpi trip_points do work: at 91 C the fan gets active. But it 
was really hard to get there....

... or even a little bit lower.... seems to be the motherboard.

Hm - your contribution was very helpful - but only the apm-part. For me 
it does not work with acpi.

I have had a closer look at the dsdt. It seems, that a Microsoft 
Operating system is expected (stingcompare). So, by passing
acpi_os_name="Microsoft Windows"
to the kernel, you enable e.g. the second battery.

ps: the ibm_acpi stuff do not work for the 600e right now, corresponding 
to the README and my experiences.
