Here is the coding for anyone else who wants to do this mod, and also to help find out what I am missing. This is what I have done so far.

Changed this code in register_ccinfo.tpl:

{if $config.disable_ccinfo eq "N"}
<tr valign=middle>
<td align=right>{$lng.lbl_cc_cvv2}</td>
<td><font class=Star>{if $config.General.check_cc_number eq "Y"}*{else}{/if}</font></td>
<td nowrap colspan=3>
{if #safeCCNum# eq ""}
<input type=text name=card_cvv2 size=4 maxlength=4 value="">
{else}

Change to:

{if $payment_cc_data.disable_ccinfo eq "N" || ($payment_cc_data.disable_ccinfo eq "" && $config.General.enable_manual_cc_cvv2 eq 'Y')}
<TR valign="middle">
<TD align="right">{$lng.lbl_cc_cvv2}</TD>
<TD><FONT class="Star"><SPAN id="cvv2_star">{if $config.General.check_cc_number eq "Y" || $smarty.get.mode eq 'checkout'}*{else}{/if}</SPAN></FONT></TD>
<TD nowrap colspan="3">
{if #safeCCNum# eq ""}
<TABLE cellspacing="0" cellpadding="0" border="0">
<TR>
	<TD valign="middle"><INPUT type="text" name="card_cvv2" size="4" maxlength="4" value="{if $smarty.get.err eq 'fields'}{$userinfo.card_cvv2}{/if}"></TD>
	<TD valign="middle">{include file="main/popup_help_link.tpl" section="cvv2"}</TD>
	{if $smarty.get.err eq 'fields' && $userinfo.card_cvv2 eq ''}
	<TD><FONT class="Star">&lt;&lt;</FONT></TD>
	{/if}
</TR>
</TABLE>
{else}

Added skin1/main/popup_help_link.tpl which looks like this:

{* $Id: popup_help_link.tpl,v 1.4.2.1 2004/11/23 10:48:56 max Exp $ *}
{if $config.UA.platform eq 'MacPPC' && $config.UA.browser eq 'MSIE'}
[img]{$ImagesDir}/question_button.gif[/img]
{else}
[img]{$ImagesDir}/question_button.gif[/img]{/if}

Next I added lng_lbl_popup to the languages area, and then I uploaded question_button.gif into /images.
