Philosophically, I think the driver should NOT modify termination on the card.
There are numerous cases where this is doomed to fail, as when there is already
a device present which also attempts auto-termination. With the HP image
scanners, for example, this will cause all sorts of trouble.
I can see having the driver issue a warning, but not actually changing things.
