Yes, I thought about that too.

The detection code seems to be fine - at least I didn't find a problem
with it. Unless, of course, the bit value to enable aux temp monitoring
was reversed in rev B, but the manual doesn't reflect that.

Guess I _must_ be missing something, but right now I have no idea what
it might be.

One thought - Tobias, can you provide sensor output from your BIOS for
comparison ?
