It is very similar to yours (see my sig) except that I'm using discrete graphics. I'm using the same exact motherboard with the same BIOS.
Can you upload and explain these patches? Thanks!
EDIT: Also, would you mind posting your BIOS changes to make it all work?
I will take some screenshots and zip everything up tonight for you, I don't know how discreet graphics will effect things but I guess you could try it without it for fault finding?
