Graphics card required, linux/)SX compatible for G4
 

Tried looking around without success, so does anyone have any ideas? I have a G4, which I need to put kubuntu on as appl£ make you pay for everything, and AFAIC, linux audio is brilliant. Presently I have a GeForce, which is unsupported as it's a G4 card. I need something good which works for the stuff my wife wants to in OSX, but works in linux.
