I'm not sure if it's a compiler bug or not, but SETREG() doesn't work on gcc4 while it's confirmed working on gcc3. (as the noted in the above mail, it looks generating byte access code) Removing __packed might also help, but bus_space(9) just works and it's a right way to go, I think. --- Izumi Tsutsui
