ATI drivers and Mac Power PC

[R.C.]

I have a Mac G5 PowerPc Dual Core.

I installed Fedora8 and all went well.   All appears to be up and 
running with no problems expect starting xserver.

I have an ATI Radeon x1900 Video card.  ATI tells me there are no 
drivers supported for the Power Pc platform.

Does anyone know of a way to run Linux on this machine with this card?

I desperately need to run a Linux based program and hoped this would be 
then answer.

Has anyone done this.

Thanks all.
