        I read the source code and it says that "special" events are
being generated for the first release and second press instead of the
regular key up/down events.  I turned on dump_adb_input in Linux and
sure enough, the "special" keycode is 0xff:

1st press:
Aug 27 19:39:42 localhost kernel: adb packet:  2c 39 ff, id = 2 
1st release:
Aug 27 19:39:44 localhost kernel: adb packet:  2c ff ff, id = 2 
2nd press:
Aug 27 19:39:47 localhost kernel: adb packet:  2c ff ff, id = 2 
2nd release:
Aug 27 19:39:52 localhost kernel: adb packet:  2c b9 ff, id = 2 

So, I tried a quick hack in adbhid_input_keycode (drivers/macintosh/adbhid.c)
to translate the events appropriately and it seems to work (at last!).

        Thanks a lot for the pointer!
