XFX Radeon HD 4650 512mb Snow Leopard 10.6.4 Black Screen?

[spark*]

Hi,

I have installed snow leopard vanilla and updated to 10.6.4. At first I followed one of the guides on here to use the 10.6.2 kexts but i got a garbled screen. So i extracted the kexts from the snow leopard update pkg and replaced them. I then went on the HCL and found someone with the 1gb version of my card, i then followed their instructions and added my device id to the kexts. I now get a NO SIGNAL message on my monitor when booting normaly and via safe boot.

I have tried DVI -> VGA and the VGA port but no hope. Please help.
