There has been some recent discussion on the CGI::Application list of just
this issue. It seems that CGI::Session does a pretty strict test to make sure
that it has a CGI.pm object and not just a compatible object. I think some
work is underway to change this so that it does some tests for the param() and
cookie() methods. So, not right now, but maybe not too much later.

how about something like this that decouples the SQL from the HTML but is
still relatively simple (and uses XHTML instead of HTML )

in perl
.
.
my $sth = $dbi->prepare(qq(SELECT val, text, (val = "$selected") AS selected
FROM whatever WHERE whatever));
my $tmpl = HTML::Template->new();
$tmpl->param(occupations => $sth->fetchall_arrayref( {} );


in the tmpl (for a dropdown select box)
.
.
<select name='whatever'>
<TMPL_LOOP NAME=OCCUPATION_LOOP>
  <option value="<TMPL_VAR NAME=VAL>" <TMPL_IF
NAME="SELECTED">selected='selected'</TMPL_IF>><TMPL_VAR NAME=TEXT></option>
</TMPL_LOOP>
</select>


or in the tmpl for a group of checkboxes, (or radio buttons)
.
.
<TMPL_LOOP NAME=OCCUPATION_LOOP>
  <input type='checkbox' value="<TMPL_VAR NAME=VAL>" name='whatever'  <TMPL_IF
NAME="SELECTED">checked='checked'</TMPL_IF> /><TMPL_VAR NAME=TEXT><br />
</TMPL_LOOP> 

this way the same SQL creates a structure that is independent of the HTML but
still not so much so that it's hard to work with.
