So the problem is a bug in the BIOS implementation. I have already contacted IBM via "Ask an expert" and posted a message to http://www7.pc.ibm.com/~Thinkpad and I really hope that they will reply. I will keep you up to date. Thanks, Dominik p.s. How ugly would a work around for the BIOS problem be? Aren't there already several work arounds for buggy BIOSes in the Linux kernel code?
