GMA950 Help

So, My issue is pretty much the same as everyone else's where I'm stuck at 1024x768. I've patched my DSDT with the DTGP method, and added in the 950 hardware addresses and such in the "Device (PCI0)" part. When I tried to run with this DSDT, it originally went directly to a white/gray screen after the apple logo, which I solved by installing an older framebuffer kext, though I'm still stuck at 1024x768. I tried putting the "Graphics Mode" directive in com.apple.boot.plist in /Library/Preferences/SystemConfiguration, and in the Extra folder. I tried this with GraphicsEnabler on and off, all to no avail. Any ideas?

Specs:
Mobo: Intel D945GCLF2D
Retail Snow Leopard 10.6.3 updated to 10.6.7
myHack 1.1
chocolate kernel (vanilla won't work with the Atom on my board)
System Profiler output:

Display:

 Type: GPU
 Bus: Built-In
 VRAM (Total): 64 MB of Shared System Memory
 Vendor: Intel (0x8086)
 Device ID: 0x2772
 Revision ID: 0x0002
 Displays:
             Display:
                Resolution: 1024 x 768
                Pizel Depth: 32-Bit Color (ARGB8888)
                Main Display: Yes
                Mirror: Off
                Online: Yes

Another issue I was thinking of was that since my monitor is technically a TV that has a vga port on the back of it, OSX wouldn't be able to detect the supported resolutions. Then I hooked it up to my main dell monitor, restarted, and still at 1024x768, but stretched this time.

Next step: I found that in my Extra folder I had IOGraphicsFamily.kext installed by myHack and AppleIntelGMA950.kext. When I removed these, I went back to the white/gray screen.
