GA-B75-D3P 10.8.5 refuses to boot. Help!

[fsckit]

I've been wrestling with this for over a week now, and I'm beginning to tear my hair out. My Hackintosh refuses to start the desktop.
You can see what it does in this video(you'll have to tilt your head sideways because of my incompetent camera work). As you can see, the screen displays the pointer, which changes to a pinwheel, and then the screen goes black with some disturbance. It seems to start in safe mode but you can't do anything with it like that.You can find a startup log here.
The build is
Gigabyte GA-B75-D3P motherboard,
Intel i5 3470(with HD 2500 gfx),
8 gig ram,
1 Tb Seagate hard drive
10.8.5.

Thanks for your help.

That looks similar to my boot issue with ML 10.8.5 on an Asus board: see here

It's only superficially similar. It seems you are having a Kernel Panic. Mine seems to be having issues with the graphics hardware.

Absolutely the same problem here.
Gray screen with for a while then just black screen with some gray artifacts.
With -x flag boots fine with 1680x1050 resolution through DVI.
I'm wondering what graphics-related options does "-x" disables ?
I'm almost sure this is graphics issue 'couse with AllpleIntelSNB* disabled also boots fine with 1024 resolution.
