Problem Running FCP v.4

I am using Final Cut Pro 4.0.1. I have a Power Mac G5, mac osx v 10.4.5,2gb ddr2 sdram and a stock 160gb hard drive with a lacie 250 gb external hard drive.my graphics card is a NVIDIA GF 6600 256 SDRAM. I am having trouble running FCP. I loaded the program fine and then when i click the FCP icon to run the program a warning msg pops up saying
"Configuration Error- This software requires certain hardware or software which is missing. ? AGP graphics card."

Can anyone tell me whats up with this and how i can fix this?

"Final Cut Pro 4 through Final Cut Pro HD 4.5 require a computer with an AGP video card for installation. PowerMac G5 (Late 2005) models (released October 19, 2005) and iMac G5 (iSight) models feature newer PCI Express video cards. Because of this, you can't install Final Cut Pro 4.x on these computers. Final Cut Pro 4.x is not supported on these computers."

I believe there is a hack for this, but I don;t know it, or know how much damage it causes, if any.
