Point was, driver state may still be dire for some hardware, but here,
the same driver for very similar looking hardware went from useless to
works fine.

My desktop box has this thing in it, which also used to be completely
useless with the in kernel driver, but now works (it's still useless,
router sits on top of that box;).  Both devices now seem to work just
fine, whereas both used to be a PITA if I wanted to use them.
