Problem here is that system vendor and platform name is not enough, the
version of the BIOS is also important. To make things worse, the problem
could be introduced into one BIOS version and fixes in another later
version.
My feeling is that trying to make guesses here will open a can of
worms we better keep closed. The strategy for now has been to search for
broken configurations and disable interrupt remapping when they are
detected.
