Problems with 4870: Resolution 4:3, GPU-Fan noisy

[Hessi]

Hi Folks!

First of all: On this system 10.5.x runs perfectly for over a year.
- ASRock Conroe1333
- C2D 1,8
- 4 GB RAM
- Asus 4870, 512 MB
- iAtkos V7, Chameleon 2 RC3

Now I want to change to 10.6
Installation with 10.6.2 (3,6/Dan1234) works well. Update to 10.6.4 with MultiBeast successful. While installation I only have to choose ATI Evoenabler and HD888-Sound.

QE & Ci seems to running, I see effects in chess, frontrow and dashboard, but not really sure if it works for real.

I have still some probs:
- GPU-Fan is running nearly at high Speed
- Resolutions are only 4:3 (have a 22" with VGA-Input – DVI to VGA-Adapter)
- System-Profiler shows "ATI HD4890" instead of 4870
- still no sound (tested legacyHD- and actual HD-888-Drivers

I tested to edit apple.boot.plist with Lizard, also tried Legacy4800Controller.kext (installed with kexthelper), but no success.

I guess I have to disable the "old" ATI-Drivers first?
Need a little help. :(

Regards
Michael
