I don't have smbus in the kernel, nor do I have any other i2c device drivers loaded in the system. I stopped using smbus when it became pretty clear that it wasn't doing anything useful for me (it could never see CPU fan readouts or anything like that when I tried it on 3 different PIII era systems). I agree a pcf(4) style interface would go some way towards solving the problem, however, solder plus 74LS05 costs next to nothing, plus the "leet value" of having a circuit schematic in the man page had to be tried out. I think we're losing out there if it's not working, though. PS OpenBSD look like they took NetBSD's i2c and ran with it... cheers BMS
