problems with Radeon HD 4570
i hope someone can help me
i have successfull installed SL 10.6.2 by Hazard on my notebook and all works fine, but i have some problems to get my graphics card to work.
Its a ATI Mobility Radeon HD 4570.
Many people write:
The only thing you have to do is, add the device id to ATI4500Controler.kext and ATIRadeonx2000.kext and reboot.
The file ATI4500Controler.kext always contain my device id.
In system Profiler there is a wrong name listed (ATI Radeon HD 4890) but the device id is correct.
My device id is 9553 and if i do the things above, after reboot i get a screen like this...
this screen appears after the boot process, instead of the desktop. Verbose mode do not show me a panic but i know, that it is caused by the file ATIRadeonx2000.kext. So i have to boot with -x and delete this file to get my desktop back.
It does not make a sense for me. What can be wrong?
Is there any other solution?
i will be thankfully for all replys and sorry for my bad english. :o
P.S. RadeonHD.kext does not work.
