isn't it more that they simply won't work with newer boots that were signed
by the new keys?  and the updated BIOS's won't boot older OS versions that
weren't signed by the new keys?

BIOS updates are often not available for sligthly older hardware, once it
goes out of production most vendors lose all interest.
