Nack. Unreliable sensors -> the default must be to NOT bind to these
CPUs. Feel free to provide a way to force the bind to happen (and still
print a big fat warning that this is a very bad idea), but do NOT make
it the default. Otherwise your driver will _never_ make it into the
kernel tree.

As a side note I'd be curious to see what Serge calls "working
sensors". We had several reports in the past of people who claimed that
their sensors were working. After looking at their numbers, I had doubt
this really was the case.
