Found out, what happened:
By accident I had ibm_acpi.ko built. Its name "ibm" was still present under "/proc/acpi".
This is not an ibm(-laptop)-machine, so ibm_acpi.ko is useless here.
"Unable to handle kernel paging request at virtual address f89e7b00":
this address corresponds to the "struct module *" of ibm_acpi.ko, which was not loaded anymore.
So the real bug here is that there is a non NULL "struct module *", where the corresponding module is unloaded.
Or so I guess.....

Best regards,
Karsten
