This is what I have in the configure area for it.
<?php bfa_widget_area('name=logo widget area&cells=2&align=9&align_2=3&before_widget=<div id="%1$s" class="logo-widget %2$s">&after_widget=</div>'); ?>
I looked in firebug to get a clue, and I can see that area is set up as a table.
table id: logo_widget_area
table class: bfa_widget_area
td id: logo_widget_area_1
div id: text-25
class: logo-widget widget_text nm
