This is a fatal error. If there are sensor chips connected to the
SMBus, you cannot reach them until the SMBus itself works. Try
upgrading the BIOS as suggested. Or try using force_addr as instructed,
just make sure you pick an unused I/O area (check in /proc/ioports.)

But it is also possible that the sensor chips are hidden elsewhere, and
the SMBus isn't used, and that's why it is disabled. I can't tell.
You'd need to ask the manufacturer for technical information.

The driver for the ADM1022 (thmc50) wasn't ported to Linux 2.6 yet,
only Linux 2.4 is supported. Not that it really matters until you can
actually reach these chips.

Do you have the source code of that tool? If you do, just check where
it gets the information from.

I also invite you to bug HP themselves about it. Ask them why
lm_sensors doesn't work with their hardware, see what they answer.
