I just installed the update on our Dev box. Here is what a required select now looks like:
<td width="190px" valign="top" class="ms-formlabel" >
<H3 class="ms-standardheader">
<nobr>Guideline<span class="ms-formvalidation"> *</span></nobr></H3>
</td>
<td valign="top" class="ms-formbody" >
<span dir="none">
<select name="ctl00$m$g_308135f8_3f59_4d67_b5f8_c26776c498b7$ff51$ctl00$Lookup" id="ctl00_m_g_308135f8_3f59_4d67_b5f8_c26776c498b7_ff51_ctl00_Lookup" title="Guideline Required Field">
</select>
<br/>
</span>
</td>
