On a system which is the same model as the reporters, which was upgraded from Maverick - with the option previously added, i could not reproduce this behaviour.
Additionally, removing the option and re-adding it I could not reproduce. I think this needs to be tested on a fresh installation or livecd... Note, having the hardware as mentioned in the bug should not be a requirement to reproduce this bug.
