Blergh. No idea why they’re using the post_id() instead, but okay. Try putting this <?php if (bb_is_first(get_post_id())) : ?> style="background-color:#FFFF99;"<?php endif; ?> after class="typo" (no need for a space). You can change the style to a class or whatever obviously, but I think that should work.
