You could execute the following sql:

UPDATE setting SET optioncode='textarea' WHERE varname='copyrighttext'

or make the change in phpMyAdmin.

As usual, be very careful doing this since an error could cause problems with your forum operation.

Edit: oh, I probably should have also mentioned that the "right" (and possibly easier) way to do this is to put your site in debug mode, then use the "Edit" link that will appear in the admincp next to the copyright text option, and change the "Option Code" field to textarea. But I thought it might be easier to do a query than to turn on debug mode just for this one change.
