Ive never done it but this looks like it could help you unlocking

Also you're going to want a mobo that supports higher PCI-E x16 bandwidth. If you notice, the second slot, when used, runs at x4 speed instead of x16.

I think you will be alright the only thing I would change is the PSU i would atleast go for a 850w crossfire certified PSU.

The only way you can flash the bios is if you have a reference card with dual bios setup. I am not for sure or not but I think you will have a next to impossible time to fine a reference card. (I am prolly wrong ) Most of the newer 6950's have a locked bios setup.
