Try different value for the transmitter.

I have tried using the transmitter and encoder values from my bios decode. The LVDS was still black without the backlight.

You can try other framebuffers. Look in mucha's thread for all possible values for ATY,ControlFlags, Transmitter, Encoder. Change one of these and try with all possible combinations for others. And all you can do is try, try, try...
Change the LVDS SenseID of all framebuffers to 07, boot with AtiConfig=framebufferName and see if it makes a difference with some framebuffer.

Have fun man. Take notes of what you've tried and than keep on trying 'till you are out of options. You'll succeed, trust me.

Tried many framebuffers, some give kernel panic, some have just vga working, some dont work at all, and Pitchecia is the only one which shows that I have 2 screens connected, but both screens are my vga screen. My lvds never got the backlight on.
