I think I solved the communication problems concerning byte writes to the gmux device. This: http://luna.vmars.tuwien.ac.at/~froemel/rmbp/patch-apple-gmux_v2.txt works reliable for me (50+ suspend/resume cycles, many brightness changes) *without* delays. I looked once more through Apple's original driver and noticed that their cmd_done waits until bit 1 is set (not cleared!) and also does the final read from GMUX_PORT_DPM_RADDR only if bit 1 is not set. Also it seems that in case of byte writes the old interface should be followed as well (Apple, why?!).
