Wrap help text in ubercart

Does someone now to wrap the instruction on the top of ubercart admin pages into the nice collapsible help in the rubik theme?

for example, in the function uc_shipping_new_package its looks like this:

  $form['instructions'] = array('#value' => t('Organize products into packages.
 Package numbers in multiple shipping types are of the first shipping type they appear in. All
 packages are given a unique ID when they are saved. Choose the default package "Sep." to
 automatically create a package for each of the selected quantity of products in that row.'));

The message is wrapped in a div bit without a class.
Any Ideas how to assign the "help" class, so that the rubik theme can handle it?

Thanks for any input.
