The first link is a patch for a totally different driver, as far as I
know not relevant to any system I have, but I guess that makes at least
3 different systems which have regressed...

I can't figure out how to turn the second link into a correctly-
formatted patch file, but since it is a one-line change I just manually
applied it on top of 6.19-rc1. This appears to fix the problem.

Thanks,
Nick
