SuSE PPC 7.1 + Geforce MX2 + Apple Pro Speakers

Hi, I want to buy a Geforce MX2 for my PowerMac G4 466. Is it possible to use it with SuSE Linux PPC 7.1. (Acceleration (2D) and (3D) included?). And the second question: My Apple Pro Speakers (external) are quiet. Only the external speakers at the headphone out jack are working. Any idea how to fix it? Also volume control is not working. (gmixer s.o.) Nevertheless SuSE Linux PPC is fantastic. Thanks Uwe.
