123	  known mode: off, blink at 0.5Hz and blink at 1Hz.
124
125	  As this LED cannot change it's brightness it blinks instead.
126	  The brightness value 0 means off, 1..127 means blink at 0.5Hz
127	  and 128..255 means blink at 1Hz.
128
129	  This module can drive the mail LED for the following notebooks:
130
