Yes, this is how you should do it. First you test on a real hardware -
if the issue is such that needs a real hardware to verify - and if it
passes, *then* you send the patch.

If you don't have access to the box, then ask someone who has.

But for the future, please do not send untested patches in a hurry,
hoping that they would work. This could cause more trouble than the
little time you might save speculating it'll all go fine.
