Graphics issues with iPC OSX86 10.5.6 installer

Image of problem here. (Large file warning)

Picture pretty much describes what's going on, but a little more backstory is needed.

I'm trying to install iPC OSx86 10.5.6 on an HP Pavilion dv6525us notebook with an external monitor, and it's having some major graphical screwups as indicated by the screenshot. Weird thing is that it worked fine the first time I plugged in the monitor, and booted the disk in safe mode. I then restarted so I could try it in normal mode, and now I get a this square, scanline-filled screen no matter what mode I boot it in. The real problem is that the mouse is really messed up, and the menu buttons have disappeared, too.

Specifications I can list off are; Core 2 Duo T5500 Merom-2M @ 1.667 GHz, Intel i945GM chipset with an integrated GMA 945 GPU, I can't quite remember the res, and a 160GB 2.5'' HDD.

Does anyone know a way to fix this, or at least make it so I can install OSX on it, and then try to fix it later?

It's video related problem as there are several unusable kexts in your installer.
You can try to delete/move them but it has to be in a writable media, USB etc., not DVD.
Try to go through with installation and delete them afterward. Use -x -v -f for boot options.
