    I use scx200_i2c. The SBC I am using doesn't work with the scx200_acb
    (different pins on the cpu after all). I would love to see it
    reimplemented using the generic interface, since there isn't that many
    lines of code involved as far as I can tell. Well scx200_acb works fine
    on a Geode LX board, but not on a Geode SC1200 board. Unless it has
    been fixed since 2.6.18, then it still doesn't work, but scx200_i2c
    works perfectly fine.
