i like this feature, and i've applied your patch to x86.git for testing, 
but i'd like to hear what the ACPI and PCI guys think about this.

Also, we should try as hard as possible to make it a blacklist instead 
of a whitelist? It would be cool to support more PCI cards/devices on 
all new(-ish) systems by default and if we didnt have to maintain the 
DMI whitelist for eternity. (a whitelist will always be incomplete and 
will lag behind reality)
