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.
