It is a relatively simple edit of tpl_product_info_display.php. This is a really well commented file, so I am sure that you'll find the right blocks of code to move - and where to move them to.
Any problems, just reply here and we'll have a look.
On the default version of this file it is lines 89-143 that get moved. Slot them back in around line 75. But I suspect yours is not a default version.
