Thanks for trying it out.

Because fixes to earlier regressions win, I think we should go with this
solution. (The commits that enabled the feature for you were considered a
regression, and the fixes to that regressed your feature. If we reverted back
to before the first regression, this wouldn't work for you anyway, I think.)

Ville, please post the patch to the list.
