i2c bus drivers (2/4)

This patch fixes i2c_smbus_write_byte() being broken for i2c-nforce2. This causes trouble when that module is used together with eeprom (which is also in 2.6). We have had three user reports about the problem.

Credits go to Mark D. Studebaker for finding and fixing the problem. We have also been contacting the module author (Hans-Frieder Vogt) but had no answer so far.

This is a serious bug fix, and I believe you shouldn't wait too long before applying it.
