I actually had applied the latest patch, though I do see that for some reason
ID 0f438086 is not recognized by the driver. The ID that was mistakenly left
out in the first patch, 0f448086, seems to be working, as you can see in my
latest `pciconf -lv`.

I also have a feeling I may have been chasing my own tail on this one. Funnily
enough, this machine doesn't actually seem to have any devices attached on the
I2C bus. I thought the indicator LEDs were accessed through I2C, but now I'm
almost certain they work through GPIO (however, I cannot get any of the pins to
change state, even with bytgpio(4), but that is another issue).
