OK.
I did the SMBus 2.0 support in i2c-core and i2c-i801, you're the
first person I know of to use it besides me, I'll look at what you did
and
I welcome any comments. Have you tested the 2.0 support?

Nobody working on 6650 or 1026; if you start, let us know,
and we will update our new drivers page to say that.
