Good to know that it will stay original ;-) iDeneb isn only working in safe mode (-x), otherwise I don't have a black screen with mouse cursor.

To the gfx cards: I was talking about the X1600 cards, not the X2600. My gfx card's core/name is Wormy. To get a working system I need these files:

ATIInject.kext, ATINDRV.kext, ATIRadeonx1000.kext, ATIRadeonX1000GA.kext, ATIRadeonX1000GLDriver.bundle, ATIRadeonX1000VA.bundle in version 1.5.24.9 (5280) AND IONDRVSupport.kext version 1.5. They are from Leo4All V3, OS X 10.5.2.

Natit I haven't tested. What are the differences betweeen Natit, Titan and ATIinject?

Quicktme 7.5.4 was working without problems, 7.5.5 is so slow that it needs about 90% on an Athlon 64 4000+. I still have iDeneb on my 2nd system, you can give me the drivers I listed above.
