Yes, i've called gericom, and there are willing to do that. But i am not
shure, that the problem is only on gericom site. With kernel 2.4.16 and all
acpi patches applied the kernel doesn't create the /proc/acpi directory, but
the cpu-fan keeps running when the kernel is booted. PCMCIA ist working
without problems. With kernel 2.4.17 /proc/acpi is created, but the fan stops
during kernel boot and will never be powered on again. That can damage the
hardware.

So why does the kernel power off the fan? If there is a userspace deamon
needed to power on the fan, it is not possible to run the machine in level 1,
or a longer installation like suse will never be possible;-)

Even to track the problems is hard to do: You have only about 5 minutes time
after boot....
