Erm... I just realised that I forgot to backup known "good" kexts. Seems that I'm not going back in this MacOS instance.... :)

PS: gee, tried of tweaking Adium again and again...

PPS: have I coped correct kexts?.. Shouldn't be here by now ;)

PPPS: gone reinstalling GU1 from scratch. btw OSX no longer detects my USB BT dongle...

i to also have had many problems with a 7600gs 512mb but its pcie.so i hope somebody can come up with a decent fix.

Latest update (installed kexts from GU1, fixed PCI ID). Result - black screen. Same black screen on external monitor connected to D-SUB, unfortunately I don't have anything DVI-like to plug to my DVI port.

do you have an vga port too or is plainly two dvi connectors?

Maybe you need a specific Nvcap value for your card, go here and post your problem there

@WinLinMac01 4 outputs: built-in LCD, D-SUB, DVI, TV-Out

My current NVCAP is
In [16]: get_nvcap('BAAAAAAAAwAMAAAAAAAABwAAAAA=')
Out[16]: '04000000 00000300 0c000000 00000007 00000000'
that corresponds to "PCIe GeForce 7 series, dual DVI", looks pretty much like what I have

WOW! IT DOES WORK!!!! and BT mouse is magically fixed :D

Congrats man!! really nice! :D

roisoft, thanks a lot for your help!
