I'm OK with snarfing up some NVRAM, as long as we have some way to check "yes,
there are NN bytes of NVRAM architected for our use".

Did I miss the memo where it says "This code will only run on chipsets that
have architected nvram space for this sort of use"?  Wouldn't be the first time
I've misunderstood what code is really doing. ;)
