"load" option broken

After updating from beta 2 to rc1, there seems to be a problem with the "load" option. This worked perfect in beta 2:

load: function(arg1, arg2) {

$.fck.config = {path: 'mod/modfck/', height:300 };

$('textarea[@name=str' + $('input[@name=strType]', arg2).val() + 'Description]').fck(/* default settings */);

But it's broken in rc1.
