I manage to fix it by booting from Chameleon-2.1svn-r1446. Now, my lion (updated to 10.7.1) identifies my ATI card :-), see image attached

 

hi,

I am encountering strange problem. I installed Lion 10.7 using Chameleon RC5-R1393 (Package by Dr Hurt). At that time, I just got 3 MB of display and 1024 x 768 resolution. I downloaded next for ATI Radeon HD5470 from kext.com (at least it was said for HD 5470). However, it didn't work. Then I came across this tutorial about EDID and did exactly like said.

 

EDID Fix

 

Then I boot with AtiConfig=Eulemur and I got my native resolution of 1366 x 768 and Lion recognized my graphics card. but then I tried to fix my sound and did something with AppleHDA next (as far as I remember), when I reboot back, the graphics was gone :( I tried to remove those kexts but couldn't do it. I also tried GraphicsEnabler=Yes, then I get a dark screen and can't see desktop. making it no has no effect.

 

Then, I reinstalled Lion again with Chameleon 2,0 rc5-r753 and yes, now I get my native resolution of 1366x753 with 4MB of display but still Lion does not recognizes my ATI radeon HD5470.

This is the excerpt from system report for graphics

Display:

 Type:	GPU
 Bus:	PCIe
 PCIe Lane Width:	x16
 VRAM (Total):	4 MB
 Vendor:	ATI (0x1002)
 Device ID:	0x68e0
 Revision ID:	0x0000
 Displays:
Display:
 Resolution:	1366 x 768
 Pixel Depth:	32-Bit Color (ARGB8888)
 Main Display:	Yes
 Mirror:	Off
 Online:	Yes

I have checked my Win 7 and the DeviceID is correct.

 

I have attached the screen shot of About This Mac (I used Extra_MacBookPro8_1 to identify my pc as macbook pro).

I have my wifi & sound working. Battery still not working despite of Voodoo battery. But I think main problem is the Graphics Card as I am not getting good graphics. I would love to get your help in this regard.
