okay got it working, but i need the dvd to start which is weired....

what i did: installed it normally, at 1 minute left i just left the installation and didnt installed anything else. but i can boot in os x now.

problems i still have:

cant boot without dvd. - stops before booting anything, stops right now before cd screen normally appears. this is after the pc loads the ub icq and mulimedia and all other devices.
5.1 sound is not working. only 2.1 alc 850 here
mouse is somehow crap, using a logitec G5 which does not work perfect. any idears hear? i could use a ps2 adapter or sth? -> solved. there are drivers...
