I had a colleague of mine (Cc'd, hi Wilken :)) test your driver. The
voltage part appears to work, we saw in0 change from 0.96 V at 800 MHz
to 1.00V at 1000 MHz. However the temperature is always reported as 0
degrees C. We dumped the value of eax after the cpuid() call and it's
0x0.

Does this mean that Wilken's CPU lacks the thermal diode? Or could this
be a bug in your driver? For reference, the CPU in question is:

processor	: 0
vendor_id	: CentaurHauls
cpu family	: 6
model		: 10
model name	: VIA Esther processor 1000MHz
stepping	: 9

If you need anything, just ask me or Wilken directly.

Thanks,
