so here are my findings so far:

hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x08


is sufficient to turn on the right functionality for the speakers; meaning:
 - 'front speaker'-channel actually controls the two front speakers within the
   macbookpro - even controlling left and right channel seperately works  =)
 - 'surround' mute-switch and volume-control (why are those not within on
   thing btw?) also work and control a third speaker in the mac, which
   really seems responsibly for surround :)

headphones do not yet work, however i made a diff of 
"/proc/asound/card0/codec#0" with and without something plugged in:
