And indeed it did. I have the function call working perfectly now. For
the benefit of others new to D6 and facing the form-theming issue, my
code footprint looks like this:

In the form generation:

$form['my_module']['#theme'] = 'my_module_form';

Implementing hook_theme():

function my_module_theme() {
  return array(
    'my_module_form' => array(
      'arguments' => array('element' => NULL),

Finally, the actual theme function signature:

function theme_my_module_form($form)

What I was missing was the hook_theme() registration and the fact that
the string passed as the #theme value does *not* begin with 'theme_',
rather, that is added by the core as it invokes the theme hook.

Thanks to all who replied.
