I'm trying to Hackintosh an old Compaq, but it just hangs on a black screen with a single white square in the corner, anyone know how to fix it?

I'm trying to install Snow Leopard (yes, 10.6, it's the last usable version for GMA), on a Presario SR5310F, I made the EFI via Dortania's guide, and after the verbose log, it shows a black screen with a white rectangle in the corner for about a second, then shows a grey screen, then goes back to the black screen and white rectangle. Here's an image:

The system has a Pentium Dual-Core E2140 (one of the Pentiums that were essentially just an underclocked C2D), 2GB DDR2, and a GMA 950. I tried a few different SMBIOSes and none of them fixed the issue.

Here's my config.plist. If anyone has any ideas, please let me know.
