ATI HD 5870 problem

[Frunchy]

Hey Guys,

 

I just set up my computer with this hardware:

 

ASUS Maximus Formula III

HD 5870

4 Gig ram

AMD Phenom II x4 3,4GHz

Intel x-25m 80 GB <-Hardrive

2 TB data disk

 

Everything runs fine and i can easily update to 10.6.4. But if I update to 10.6.5 the computer reboots and just show the wallpaper but in full 1080p resolution The same happens if I use the kext from Netkas here.

Any Idea how to fix it?

And the sound doesn´t work at all but this is not as important as the graphic

 

Thanks for help, Frunchy:)
