Can anyone help me with a 4870x2 driver or point me to a tutorial. also sound issues.

[lgevo]

Hey i just installed osx 10.6 (yes plain 10.6 to afraid to update it more) on my
GA-MA770_UD3
AMD Phenom x4 3.0 ghz
4GB Corsair 1066
ATI 4870x2
ACL888 onboard sound
Creative labs SB X-Fi pci card

Got internet working. Currently on it. Got it partitioned with win7 perfectly.

Last issues are sound and Video. I been searching for 4870x2 driver but all the ones i see say there for 10.6.7. An i have yet to find a working sound driver for ACL888 or the creative labs SB X-Fi card. I have VoodooHDA.kext with HDAenabler.kext.
And for my video card i got ATI4800controller.kext, EVOenabler.kext and HDradeon.kext(not sure if its needed).

Please any help would be great!
