Here's the patch as promised.  Took the code from smsc47m1.c.  It
currently only changes behaviour for the IT8712F since I cannot test
on any other IT87-chips, and the comments in sensors-detect made me
uncertain whether they really use the same key/exit sequence.

Also changed sensors-detect somewhat to support longer devids and exit
sequences.  Don't know if you'll approve my perl though...
