PCI-E Nvidia 6600, 7300, 7900 not work in Lion with DSDT (stuck at gray screen)

Does anyone have any experience?

I tried to use the 10.6 ones, but it end up saying "The following symbols are unresolved for..." _Biosreadbytes..
Boots but no QI/QE. I tested with photo booth, but no video can be seen when I plug in camera

I did try NVEnabler64, with 6600 and 7900 = gray screen, with 7300 it panics.. (same thing as DSDT method)
