I feel if AMD wanted to they could whip together a miner ASIC in a month that would blow everyone else away

They would probably be able to do it that fast, yeah. Compared to their CPUs, the ASIC are far less complex...
I'd be far more worried about Intel doing that than AMD though

I think AMD is still the "underdog" more likely to embrace something non-mainstream like Bitcoin
We should start a write in campaign...
