Are you using the kernel Cache?

I think the problem could be related to the graphics card.

If I understood you right, it does boot to desktop with "-v UseKernelCache=NO npci=0x2000"? Or must you have -x included to boot? If it's possible to boot without including -x, then should be kernel cache issue and you can rebuild it in terminal using "sudo touch System/Library/Extensions" but you should repair file permissions first. If it will only boot when -x is included, issue is with a "optional" kext such as graphics acceleration. In this case, also try a permission repair first and then see if you can boot with only "-v UseKernelCache=NO npci=0x2000". If you have multiple monitors or can try other video outputs, check them all for possible image showing on wrong output.

Then issue is with your kernel cache, make sure it's rebuilding properly when done via terminal by watching console.app for any errors. Were you using Extra/Extensions/ folder at all? If so that is other possible problem.

Use Kext Wizard to rebuild your kextcache and correct any permission issues.
