Even if you don't have other platforms for testing, I'm thrilled when
folks point out issues with them and (given time and inclination) post
patches for them.

I'd much rather fix *all* instances of the problem than just one, even
if we can't test them all.  Frequently driver maintainers will review
and test patches for their hardware even if we can't.
