Hm, I've hoped I could chicken out and to the non-limited thing for
3.6 ... as you say, it's a bit late to do such a change in after -rc5.
So I guess the question is: How much does not having this patch break
panels, i.e. can some mad vt-switching restore them or are they
bricked for good until reset?
