HD3850 Boots In Safemode But Not normal (SL)

Hello all!


Ive just downloaded snow leopard 10.6 and everything is working fine except my videocard!

These are my specs:


P5W DH Deluxe



And the problem is my videocard is running fine in safemode! I can do everything in there, but i would like to boot in normal mode because my sound is working also then, and then i can make it dual boot. So is there any fix any kext file going around with a fix? Or how long do i need to wait for a fix? Or aint there gonna be a fix?


Well thanks in advance..!

I was in the same boat with my HD3850, but after removing all the ATI kexts from /system/library/extensions I can at least boot without using safe mode without a kernel panic.


Of course hardware acceleration is not working, and my resolution is limited to 1400x1050... so it aint perfect.


I haven't found anything replacement kexts that work yet in Snow Leopard, and from what I gather the HD3850 is not supported very well since apple only uses the HD3870. So a fix might not be forthcoming...


Let me know if you figure it out, I'll keep KPing myself trying to get it work too.
