You ought to pick different values on different runs 0x00, 0xFF, 0xAA, 0x55 etc...

So a zillion people should lose a chunk of RAM because of what is probably an obscure bug in a single version of a piece of SMM code on two systems total ?
That appears to be totally out of proportion - plus the defaults are *irrelevant* for mass user coverage. If you want large scale coverage ask the Fedora, OpenSuSE and Ubuntu people to turn it on for a testing kernel release and report back.
