Ok i got a powermac g4 'gigabit ethernet" and i have a at radeon 9000 pro i knoe they made a mac model and this isnt it but i heard something about being able to flash the card or something to make it work HELLLLLLP
Over on Cube Owner they have a guide on how to flash a Peecee graphics card to a Mac rom. It is difficult, but the rewards speak for themselves, especially when you have a peecee graphics card in your Mac for half (or less) the cost of a Mac one.
