Yes, I have the same problem and I tried it on three completely different
boards: ThinkPad 600E, some generic p2 board, Intel ISP2150 server board.
the intpm0 is recognized, smbus0 is found, smb0 is attached to it, but
ioctl SMB_READB fails.
I contacted the author of lmmon and he doesn't know if it's a change that
was made to freebsd lately since he uses it with Asus P2B and it
simply works either with /dev/io or smb.
I think that it might be a problem with this driver, however browsing the
source didn't reveal a source of failure, but I'm no kernel hacker :(
Here's a snip from my mail to him:

Chris also stated that:
"I wonder if your board is unsupported. intpm(4) may not be able to work
if so."
I also tried adding various iic devices:

but it makes no difference.
Perhaps someone could shed some light on it.
