Is there any capability in the loader to do such things as get/set a PCI
config space register?

Looking at the  man page I'd say not, but there is mention of
some PNP capacity (though not currently working).


Reason..

ASUS disable the SMBus on their new mother boards and have no BIOS entry
to enable it, but it can be enabled from the PCI config regs. Without
it you can not easily read the voltages, temperatures and Fan speeds.

You can use pciconf to enable it but by then it's too late
for the ichsmb(4) driver to find it. The only other answer is to 
enable it, and then kldload the ichsmb module, but the best answer
would be to enable it from the loader so that it shows up on the PCI
bus during normal boot.

(ASUS need to get a clue on this.. a BIOS option would be real nice..)
