Torben,
that is the cleanest example of corner code i have ever seen - no hacks at all.
The column code is nearly hack free - again the best i have seen.
But these are fairly simple div manipulation examples the problems i have observed (except for Mac IE) are not that they don't work, but that they don't look quite right - which for our main header is super important.
Maybe someone who is a better css whiz than me can unify it all, but I don't think we want to go down the css hacks road - even if every movable type blog thinks they are ok.
