No graphics in 10.5.5 (kernel 9.5.0, build 9f9)

Because I couldn't get my GeForce 9300m GS to work on 10.5.4 (or any version) I was waiting to get a pre-release of the new update (10.5.5 with kernel 9.5.0 and a graphics update). The problem I had was that as soon as I added my DevID to NVDAResman.kext, the system.log showed this line:


kernel[0]: NVChannel(GL): Graphics channel timeout!


And I got a blank screen.. Leopard did boot however..


But after installing 10.5.5 with the graphics update (BTW, 10.5.5 should support Geforce 9m series because it was already in NVDANV50HAL.kext), I still get the same error & blank screen.


kernel[0]: NVChannel(GL): Graphics channel timeout!


But I also get this message:


VGA: match category IOFramebuffer exists


Now, I've tried everything from NVCAP settings to GFX strings, but everytime I want to enable Hardware acceleration I get a blank screen.. I hope someone knows what to do..


These are my specs:

Intel Montevina (mac users: Cantiga) notebook

Intel Core 2 Duo P9500 @ 2,67GHz

Intel PM45 chipset + ICH9M

nVidia GeForce 9300m GS 256MB

4GB DDR2 800MHz

Try installing NVKush, then put the gfx id in the plist of NVKush.kext, and GeForce.Kext as well as the mentioned above.
