I used to do that back in the days when I used UBB. For vB, I haven't seen a mod so in your postbit_legacy template cut this code out (back up template first!):
<td class="alt2" width="175">
<div id="postmenu_$post[postid]">
<if condition="$show['profile']">
<a class="bigusername" href="member.php?$session[sessionurl]u=$post[userid]">$post[musername]</a>
<script type="text/javascript"> vbmenu_register("postmenu_$post[postid]", true); </script>
<else />
$post[musername]
</if>
</div>
<if condition="$post['usertitle']"><div class="smallfont">$post[usertitle]</div></if>
<if condition="$post['rank']"><div class="smallfont">$post[rank]</div></if>
<if condition="$show['avatar']">
<div class="smallfont">
<br /><a href="member.php?$session[sessionurl]u=$post[userid]"><img src="$post[avatarurl]" alt="<phrase 1="$post[username]">$vbphrase[xs_avatar]</phrase>" border="0" /></a>
</div>
</if>
<div class="smallfont">
<br />
<if condition="$post['joindate']"><div>$vbphrase[join_date]: $post[joindate]</div></if>
<if condition="$post['field2']"><div>$vbphrase[location_perm]: $post[field2]</div></if>
<if condition="$post['age']"><div>$vbphrase[age]: $post[age]</div></if>
<div>
$vbphrase[posts]: $post[posts]
</div>
<if condition="$show['reputation']"><div><if condition="$show['reppower']">$vbphrase[reppower]: $post[reppower]</if>$post[reputationdisplay]</div></if>
<div>$post[icqicon] $post[aimicon] $post[msnicon] $post[yahooicon] $post[skypeicon]</div>
</div>
</td>
And paste it after this code:
<!-- / edit note -->
</if>
</td>
