In that code you have more than one row in title text if description of child forums present, so I suggest to split it in two different headers: rounded one will be shown if title has only one line of text, standard one will be shown if more than one line of text. Something like this:

<if condition="$show['forumdescription'] or $show['subforums']">
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
	<tr>
		<td class="tcat" colspan="<if condition="$vboptions[showmoderatorcolumn]">6<else />5</if>">
			<a style="float:$stylevar[right]" href="#top" onclick="return toggle_collapse('forumbit_$forumid')"><img id="collapseimg_forumbit_$forumid" src="$stylevar[imgdir_button]/collapse_tcat{$collapseimg_forumid}.gif" alt="" border="0" /></a>
			<a href="forumdisplay.php?$session[sessionurl]f=$forum[forumid]">$forum[title]</a>
			<if condition="$show['forumdescription']"><div class="smallfont">$forum[description]</div></if>
			<if condition="$show['subforums']"><div class="smallfont"><strong>$vbphrase[subforums]</strong>: $forum[subforums]</div></if>
		</td>
	</tr>
</table>
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<else />
<table width="100%" cellspacing="0" cellpadding="0" border="0">
	<tr>
		<td width="20"><img src="$stylevar[imgdir_misc]/corner_left.gif" width="20" height="20" border="0" alt="" /></td>
		<td class="tcat" width="100%">
			<a style="float:$stylevar[right]" href="#top" onclick="return toggle_collapse('forumbit_$forumid')"><img id="collapseimg_forumbit_$forumid" src="$stylevar[imgdir_button]/collapse_tcat{$collapseimg_forumid}.gif" alt="" border="0" /></a>
			<a href="forumdisplay.php?$session[sessionurl]f=$forum[forumid]">$forum[title]</a>
		</td>
		<td width="20"><img src="$stylevar[imgdir_misc]/corner_right.gif" width="20" height="20" border="0" alt="" /></td>
	</tr>
</table>
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center" style="border-top-width: 0;">
</if>

<if condition="$childforumbits">
<tbody id="collapseobj_forumbit_$forumid" style="{$collapseobj_forumid}">
	<tr align="center">
	  <td class="thead" width="50"></td>
	  <td class="thead" align="$stylevar[left]">$vbphrase[forum]</td>
	  <td class="thead" width="30%">$vbphrase[last_post]</td>
	  <td class="thead" width="50">$vbphrase[threads]</td>
	  <td class="thead" width="50">$vbphrase[posts]</td>
	  <if condition="$vboptions[showmoderatorcolumn]">
	  <td class="thead">$vbphrase[moderator]</td>
	  </if>
	</tr>
$childforumbits
</if>
</tbody>
</table><div style="padding: 5px 5px 5px 5px;"></div>
