x1600xt + Natit = CI but no QE

I just finished installing Natit for my Sapphire x1600xt.


I am running the 10.4.8 kernel from mifki and everything is working great...well almost. After the install I noticed that the graphics tests performed great in Xbench but then noticed that I QE was not working even though System Profiler says its supported.


I have determined the cause to be IOPCIFamily.kext.


After replacing the kext with one from 10.4.6, QE works but the graphics performance drops by a lot. When using my GMA950 instead with the 10.4.8 IOPCIFamily, all is fine.


Is anyone else having this problem? Does anyone have a modified 10.4.8 kext that will allow for QE without the huge performance hit?


Here is my graphics section of System Profiler if needed:

Hello, well I Have the same Ati chipset on my video card, but I think the problem is the ID 71c0, is not compatible with Natit, I´m use JaS 1.4.8 Intel SSE3 DVD and select in Install options for compatibility with PCIe Ati X1600 and my XT works like a charm, and I have QE+CI on Xbench, make a New install with these DVD and Try again, cause the 71c0 cards are hard to full install with a modified Kexts and a old bad installations.
