Are you sure your moinboard does contain monitoring
hardware that is supported by lmmon?

I have a very similar VIA C3 system on an EPIA PD10K
mainboard.  The viapm driver supports it fine, but
it doesn't have lmmon-supported monitoring hardware,
unfortunately.  Here's dmesg, pciconf and sysctl
output if you're interested:
