[un]surprisingly it's actually the same as gscsio(4). here's a port
of that code to glxpcib(4). i don't have the hardware at hand, but
i encourage you to test (:

alix2d2 LM86, no hw.sensors
I have an alix2d2 running OpenBSD 5.0. There are no hw.sensors.
The producer says there is an LM86 on board, which is supported by the
maxtmp driver. It appears the driver is present in generic. I tried starting
sensorsd but got:
daemon:Feb 17 13:12:04 T1 sensorsd[10445]: startup, system has 0 sensors
How can I read the temperature of my alix2d2 running OpenBSD 5.0?
