Sure. If yourself or Jeremy could send over the tarball?
I don't use any hardware monitoring on it currently.

Interestingly, I just tried on a couple of our webservers. Dell 
PowerEdge 860's with ICH7 running 7.0-STABLE, amd64. Loading the ichsmb 
module gives:

ichsmb0: <Intel 82801GB (ICH7) SMBus controller> port 0x8c0-0x8df at 
device 31.3 on pci0
pcib0: no PRT entry for 0.31.INTB
ichsmb0: can't get IRQ
device_attach: ichsmb0 attach returned 6
