macluishj, You are lucky man =) I have the same laptop. Here is my DSDT with some patches.
You should patch AppleIntelCPUPowerManagement.kext to make your processor work. If you use VoodooHDA.kext, you should delete patches from Device (HDEF). And my video section is designed fro framebuffer Osmunda.

Pentahex I want to fix it. If you find solution, please post here.

Pentahex =) glad to help)
VGA with this personality works fine. But I have no way to test HDMI.
These DSDT-sections, I found all little by little. Basically, it's my numerous attempts. =)
And question to you: Do you have a problem with 16 bit color?
To test, just open this image. Do you see a sharp gradient?

Hi, Pentahex! I have never got black or blurred screen. I didn't encounter this problem, since I picked the correct personality. But every boot I have distorted colors. I use Chameleon bootloader, because its performance is higher (In OpenGL EV ~1450 Cham, ~600 Chimera). Sleep just worked for HDMI and VGA. To enable it on LVDS I have used DualLink patch and DualLink transmitter.

I have got framebuffer information on this forum. But there is nothing important in this DSDT section (except DualLink).
Anyway, if it helps, here is my Device (PEGP).

I think, you can use my personality to success.
Once again - Dual Link Transmitter (0x10) don't work without Dual Link DSDT-patch!

In my case, it is in the section Device (PEGP), there you must create Method (_DSM), If it's not there. Like this

To Enable sleep. you should use this patch
"AAPL00,DualLink",
							Buffer (0x04)
							{
								0x01, 0x00, 0x00, 0x00
							},
and transmitter in your framebuffer should be the same, and in the redsock dump (0x10, If I am not mistaken)

And if it helps, my personality
