I have a Mac Pro 1.1 running OS X Lion. It runs flawlessly in Safe Boot, but freezes in Normal boot. The RAM has been checked with Rember, the hard drive was swapped, formatted and OS X Lion installed....no change. The video card was moved from Slot 1 to Slot 4....no change. What do I look for next ?
Got a tip for us?

What I would try...
boot in "safe boot mode" and make a Carbon Copy clone to another drive, now try selecting this cloned copy as the boot drive, let it boot in normal mode and see what happens.

No, not in Lion.
Do you have any other PCIe cards installed in your Mac (or any other peripherals) except GPU, keyboard and mouse?
Maybe have a spare graphics card laying around just to test if it will boot with it?
Can you boot in verbose mode and see at what line OS X loading stops?
