Sorry for the dead horse revival, but I was just looking at an SMBus
spec today, and it reminded me that the specs I look at always seem to
show the address left justified; 8 bits big.

See page 10 of this doc:
http://www.atmel.com/dyn/resources/prod_documents/doc5226.pdf

or page 6 of this one:
http://www.nxp.com/acrobat_download/datasheets/PCA9555_8.pdf

the documents show the register pictures like 0xAX, not 0x5X+1bit :)
