+If you had a page which only contained a form:
+
+<?php
+function mymodule_page_form() {
+  // form definition here
+  // ...
+  return drupal_get_form('mymodule_page_form', $form);
+}
+?>
+
+then just change it to:
+
+<?php
+function mymodule_page_form() {
+  // form definition here
+  // ...
+  return $form;
+}
+?>
+
+If you used another form_id or a callback (which is now called function_prefix):
+
+<?php
+function mymodule_page_form() {
+  // form definition here
+  // ...
+  return drupal_get_form('myform_id', $form, 'mycallback');
+}
+?>
+
+that becomes:
+
+<?php
+function mymodule_page_form() {
+  // form definition here
+  // ...
+  $form['#form_id'] = 'myform_id';
+  $form['#function_prefix'] = 'mycallback';
+  return $form;
+}
+?>
+
+Finally, if you had a page which contained a form and other things, then you need to move the form to a separate function:
+
+<?php
+function mymodule_page_form() {
+  // form definition here
+  // ...
+  $output = drupal_get_form('myform_id', $form);
+  // ...
+}
+?>
+
+then you will need:
+
+<?php
+function mymodule_foo() {
+  // form definition here
+  // ...
+  $form['#form_id'] = 'myform_id';
+  return $form;
+}
+function mymodule_page_form() {
+  $output = drupal_get_form('mymodule_foo');
+  // ...
+}
+?>
+
+Finally, system_settings_form now just needs an array, remove the 
+form_id.
