Re: [PATCH RFC] function probe_roms accessing improper addresses

I don't think DMI checking is going to work, since (a) as you say,
there's a risk that the ID will inadvertantly change over the lifecycle
of the machine, and (b) there may be other machines. So if it's not
possible to handle this by catching the MCE, I think we have two
options:

1) Declare that any x86 hardware supported by Linux *must* support
probing in this address region

2) Don't call probe_roms() by default, but leave it up to the graphics
drivers. If they can get the rom by any other means then don't call it.
