Use the no blocks function of theme('page') to prevent blocks and print
the regions yourself? Use a panel or panels everywhere? Use context.module?

Create a completely different page.tpl.php with different regions and
then place only that module's blocks in those regions? Then the regular
regions won't get printed?

Have that page appear in a different theme; that theme has separate
block UI and so that theme could configure only the needed blocks.
