I had to place profile module's fields in my own form.
Thanks to this blog http://echodittolabs.org/profile-module-form-wrapper, I managed to do it for Drupal 6.
Here is a snippet :)

function my_module_menu() {
  $items['my_module/form'] = array(
    'title' => 'My form',
    'page callback' => 'my_module_form',
    'access arguments' => array('access content'),
    'description' => 'My form',
    'type' => MENU_CALLBACK,
  );
  return $items;
}

function my_module_form() {
  return drupal_get_form('my_module_profile_form','Personal Information');
}

/* 
WRAPPER FUNCTIONS FOR PROFILE.MODULE FORM 

The profile form is usually only available on the user editing form.
Some wrapper functions are necessary to make it work elsewhere.
*/
function my_module_profile_form($user,$category)
{	global $user;
	if(module_exists('profile'))
	{
		$user = user_load(array('uid' => $user->uid));
	
		$edit = array();
		foreach($user as $key => $value)

			if(preg_match('/^profile_/',$key))
				$edit[$key] = $value;		
		
		$form = profile_form_profile($edit, $user, $category);
				
		// now let's pretend we're in hook_form_alter							
		
		// add a submit button
		$form['op'] = array
		(
			'#type' => 'submit',
			'#value' => t('Submittt'),
			'#weight' => 30
		);
		
		// pass along the $category parameter as a hidden value
		$form['category'] = array
		(
			'#type' => 'hidden',
			'#value' => $category,
		);
		
		return $form;
	}
}

function my_module_profile_form_submit($form, &$form_state)
{	
	global $user;
	if(module_exists('profile'))
	{
		$r = profile_save_profile($form_state['values'], $user, $form_state['values']['category']);

		// reload the user with the newly-saved info
		$user = user_load(array('uid' => $user->uid));
		drupal_set_message(t('Your order was saved.'));
		return $r;
	}
}

Here is a snippet to pull the options from a profile field select list into an array for use in your forms. Use this if you're building a form in a module, and want to populate your forms options with data from the profile module (specifically a list type, with options):

$results_raw = db_result(db_query('SELECT options FROM {profile_fields} WHERE name = "my_profile_field"'));
$results = split("[\n\r]", $results_raw);
$options = array();
foreach ($results as $result) {
  if ($result = trim($result)) {
    $options[$result] = $result;
  }
}

You can then put the $options array into your form definition like so:

$form['my_select_list'] = array(
  '#type' => 'select',
  '#options' => $options,
);

I hope this helps someone in the position I was in a couple hours ago ;)
