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.
