OK, let's form a club ;) Looks like we both like replying to ourselves
today.

Step 1 is to check that the p4b_smbus trick works for you. Just change
the relevant define and try (see my other post).

If step 1 is successfull, i2c-i801.c should work out of the box (it's
the same SMBus device after all). So there is no step 2 ;) Ditto for
sensors-detect, it should work out of the box (we just can chanhge the
description string from "DB" to "DB/DBM").

If it works (whether or not you actually find something on the bus), we
of course want to do update the files in our CVS repository.
