Lion, Ati 4850 and Sleep

[uzmi]

Hi:

I have a graphic Ati 4850 1GB ( http://es.gigabyte.c...r485mc-1gh.html ).

I modified the ATI4800Controller.kext to make it work with Lion .I added the graphic card ID.

 

 

I also modified Name (_UID, Zero) by Name (_UID, One) in DSDT file.

 

 

Finally I added "Graphics Enabler->Yes" in the org.chameleon.Boot.plist file.

 

 

Everything works but Sleep-Wake. When he wakes up, the monitor does not turn on. The screen resolution is 1440x900

 

 

As the graph has two DVI connectors, connects the monitor to the second DVI port.

Sleep-Wake now works fine but the resolution changed to 1400x1050 and everything looks blurred.

 

 

I tried to add the resolution 1440x900x32 in org.chameleon.Boot.plist file, but no image appears when I restart and get a message "Out of range"

I also tried the program SwitchResX4 but this is what I got:

 

 

I added the graphic in the DSDT file and delete the line "Graphics Enabler-> Yes" in the org.chameleon.Boot.plist file.

 

 

It is the same as before, the connector @0 does not work, and the connector @1, does.

 

 

IORegistryExplorer image partial with Chameleon injecting the graphic:

 

 

and here's another picture with the DSDT and Ati graphics:
