Read sensor values (fan speed, temperature) from nct6792 chipset?

Hi,

is it possible to read sensor values (fan speed, temperature) from nct6792 chipset in FreeBSD? I'd like to watch the fan speed and send an alarm e-mail when the fan fails.

Linux has a driver for it and can show values:
Code:
# sensors
coretemp-isa-0000

Package id 0:  +27.0°C  (high = +80.0°C, crit = +100.0°C)

Core 1:        +23.0°C  (high = +80.0°C, crit = +100.0°C)
