Right, that's what I meant - the drivers are now so generic that they
probably shouldn't be selecting everything they could possibly work
with.

I think this is a result of the drivers originally being very specific
to a particular setup and gradually getting made more generic, if the
driver can only be used on a specific machine then the selects make
sense but that's no longer the case for these drivers I think.
