I am having the same problem with my current build. I have built a few hackintoshes and this is the first time I have had this problem, but I think it has to do with cpus=1 and the correct VoodooTSCSYNC.
I have used my HD 6870, my GeForce 9600 GT, and my GeForce GTX 260.
All with the same results.
Went out and got a GeForce 640 to try and with;
-v GraphicsEnabler=No npci=0x3000 cpus=1
I got to the install window.
