I would use "joschiwelt" (without the quotes) on condition that string isn't used in other inline JS or in paths to non-inline JS. Another candidate could be "mk-boxed-layout".
Alternatively you could wrap the JS in noptimize-tags, cfr. the FAQ for more info on that.
Do take into account it might be necessary to also exclude jquery (or to "force JS into head", as your inline code relies on that.
hope this helps,
