Shoot, the register values didn't change. So we're looking at the
wrong thing here. Darn...

Please run 'isadump -k 0x55 0x2e 0x2f 0x8' and 'isadump -k 0x55 0x2e
0x2f 0x9' and post the output. We have to look at a different logical
device.
And please also post the output of 'lspci -vv -nn' and the full output
of 'sensors-detect'.
