Just out of curiosity, are there any Swedish or Norwegian company or
personal names that are written with o-diaeresis or o-slash, and would
any of them be offended if their names were displayed with the one
that they do not normally use themselves in printed matter, business
cards, logos, etc?

I guess you meant resolution instead of registration in the case of
the browsers. In any case, I hope that these browser developers do not
start implementing such mappings unilaterally. I would hope that they
would discuss this with others (e.g. on this mailing list), so that
there is some hope of interoperability.
