Hi there again.
My Kalyway Hackintosh worked just fine with my old 7600GT, but my 7600GT died because of... playing fallout 3.

Anyway: I had to buy a new graphics card, and it's a GeForce 9800GTX+.
But... Guess what. Leopard refuses to boot. It stays in the apple boot screen forever.
When in text-boot mode, it stops somewhere around the NVinject part.

I have Read/Write access to my Mac partition on my Vista, so if any of ya got any tricks up their sleeves to revive a Leopard after a graphics card exchange, then I'm ready to try it all.
