The 2.6 i2c-dev bus numbers don't necessarily match i2c-adapter bus
If you rmmod and re-insmod a bus driver, the driver seems to get its old
i2c-dev bus number back. But the i2c-adapter number increments.
Don't know why. It would be much better if they matched.
Most userspace tools need the i2c-dev numbers since they are going
to use /dev/i2c-x devices to access the bus.
The bus numbers reported by libsensors apps are the i2c-adapter numbers.
I think it has to be that way since we don't need i2c-dev and therefore
can't count on it being installed.
So you can't take a bus number from 'sensors' and then take that
number and use it in 'i2cdump', for example.
