I would just do a Retail Install. Distros don't always get what you need and you start from scratch. I would use EMpire-EFi and the once you installed the OS and booted into it with the Empire-EFi CD I would update to 10.5.4 and would get the legacy 10.6.4 kernel and run myhack installer.


Its the way i did it

if you could downgrade your card to the ATi 57xx series that would be great because Snow Leopard now supports them. Audio and Ethernet should be much of prob.

But if you still want to use your 480 GTX i would go look on netkas.org
