True, but all other x86-specific hwmon modules are in
package/kernel/linux/modules as well and I'd rather wanted it to be
consistent.

Sorry for the lack of a more detailed description.
The problem here is that the W83627EHF driver also claims the NCT677x
hardware but doesn't support all features (according to
Philip Prindeville). I reckon he can provide more information regarding
which features which are available when using the nct6776 driver are
missing in the w83627ehf driver on NCT677x hardware.
