SMBus is a superset of i2c.  SMBus controllers are i2c controllers
with a higher-level interface than what you're proposing.

I really suggest you read it.  There's also some framework code from
Andy Doran that I have that I should probably forward along to you
(he did this work a while ago to talk to i2c temperature sensors that
are accessible through the SMBus controllers on many modern PCs).
