Re: [ACPI] Re: IBM Thinkpad A31 | ACPI problems

Dear Kenichi,

sorry - i did not see Andy Grover's reply to Sandro earlier on. 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?
