DMI or probably IBM ssid values. Presumably IBM have somewhere they look
for this information ?

Making the driver only load on a DMI match or with an option "force=1"
which tells people to submit the DMI data would rapidly fill a table if
IBM can't answer the general question.

At the very least it should check for an ibm laptop first.
