Sapphire ATI Radeon 4830 (Lion)

[revertive]

I have installed lion on my desktop pc, the first thing i did was copying FakeSMC.kext to my extension folder to make it boot. Then found a kext to make my network card working. But now i'm trying to get my graphics card working.

 

Specs:

 

Intel Pentium E5200

Asus P5B-Premium

4 GB 800Mhz DDR-2

750 GB HDD (Windows)

80 GB HDD (OSX)

Sapphire ATI Radeon 4830

ACER P246H

 

At first i tryed Netkas 10.7.1 qe/ci exotic patch, and when i reboot my display go's black and says "input not supported" which seems to indicate that a wrong resolution is used.

 

Then i tryed to set the resolution with com.apple.Boot.plist

<key>Graphics Mode</key>
<string>1024x768x32</string>

But i didn't seem to have any effect.

 

When i boot with kernel flag "-v" i see this:

** Device in slot --1 **

So it seems the kext looks for a device in the wrong slot or something.

 

Does anyone know how i can make my graphics card work?

I've succeeded to login to my desktop, i used VNC to login and change my resolution. It works but the max resolution i can successfully choose is 1600x900 @ 75Hz (60 Hz doesn't work). My displays native resolution is 1920x1080, but when i select that one it says "Input Not Supported".

 

And i have a new line thats keeps popping op in dmesg,

 

IOSurface: buffer allocation size is zero

 

My display is a ACER P246H.

I hope there is someone who had this problem to and knows how to solve it, thanks in advanced.

 

EDIT: It seems that every resolution works as long as i can select 75Hz, but at 1920x1080 i can only select 60Hz so it doesn't work. Does someone know if there is a way to for 75Hz @ 1920x1080?
