yeah @.@ that have to be your problem XD
Man this happend to us before~ you ran that kext and your system stuck in the same place or something :/
Somehow this works for others users, maybe is a different chipset
The funny thing is that in System Profiler it says that my Core Image is Hardware Accelerated and QE is Enabled with the kexts from the 10.5.2 Kalyway DVD, but it really isn't the mouse leaves artifacts from the web browser every time I scroll, and I can't change my resolution. When I update to 10.5.4, DVI gets a black screen with the kexts, and VGA gets a a pink screens with vertical lines going through.
yeh, maybe if you wanna better support on video is better to buy a new one, dont have to be expensive, just check the HLC :D
Maybe ATI 3850 ;D
