Hi all I'm new I just installed OSX last night on my old box and its working pretty decent as I'm using it to type this but the only thing left for me to be content is for my AGP radeon card to support QE/CI and have higher res then 1024x 768 are there any packages I can use to install and make it happen or what do I do?

Here is my setup:
Distro: Kalyway 10.5.2
Motherboard : Gigabyte GA-K8U-939
Chipset : ULI M1689
Graphics :ATI Radeon 9800 PRO
Networking: Realtek RTL8139
Sound : Soundblaster Audigy 2 ZS
Optical Drive = Magicspin ?
