2 solutions i can think of:
1. edit your theme, and move the $xoops_banner variable (or whatever it's named) to the html column location that you would like it to appear in, and manage your banners using the XOOPS banner administration, then implement a hack into the code to display or not display the banner based on the module name
or
2. put the banner html into a block and display it on whatever module pages you prefer.
