OK looking in the specs on the w83627ehf bank0 3b-3f are the minimum fan
speeds, on the n6776f they're not defined.
There appears to be a dual usage register "CPUFAN MODE Register / CPUFAN
TOLERRANCE Register - Index 02h (Bank 2)" and the actual limit is readable
in (CPUFANIN) Fan Count Limit High-byte Register - Index 3Ch (Bank 6), but
that's read only. Maybe it's better if we handle the fan lo limit within the
driver rather than through the chip.

Ian Dobson
