Previously part of [0], now a patch series on its own.

This patch series cherry picks two commits from [1] and applies one fix
according to [2], which should answer Gerd's comment [3] on previous
patch.

RFC as I believe it needs a proper review from both authors of first two
commits.

Looks sane on a quick glance.  I'd tend to squash patch #3 into patch #2.
Doesn't make much sense standalone though ...

take care,
