Curious. I wonder why xmbmon-2.0 isn't in ports yet? The need, or
not for SMBus support in the kernel depends on exactly which chipset
you have on your motherboard. Mine isn't supported through the ISA
bus, even with version 2.0, but the SMBus stuff just works.

Wow --- how cool is that? Well, according to my temperature monitors,
it's 17.3 degC down from the previous day's average. Doing the same
job with pciconf is a matter of working out by hand what registers to
alter on which device, but why bother when fvcool already knows the
answers?
Cheers,
