In Drupal 6, there are several problems with having 2 forms on a page
using the same form id. You will probably need to implement hook_forms()
to create a new form id (e.g., 'YOURMODULE_user_login_block_premium')
that maps to the 'user_login_block' callback (see
http://api.drupal.org/api/function/user_forms/6 for an example of how
this is done). Then you can drupal_get_form() the two forms using
different ids, and hook_form_alter() them differently based on the $form_id.
I'm hoping Drupal 7 fixes the remaining bugs with multiple instances of
the same form on a page. I'm not sure what all of them are yet, but for
starters: http://drupal.org/node/766146.

Hi Earnie,
Thanks for the answer and that's one of the things to do, but my
problem at the moment with that path is that in hook_form_alter there
doesn't seem to be anything that I can use to identify which block it
is. Am I missing something obvious?
If there is nothing in the $form then what I think I actually want to
do is use some code to generate the form and as I have access to the
$form array to put in my own validation rule or hidden $form element
or whatever to distinguish between the different blocks. So I'm
trying to generate the user_login_block myself so I can alter the
$form array but can't get it to work. In my block code if I call
drupal_get_form('user_login_block') for the block content everything
is fine but I can't alter the form object. So I'm trying to do the
same steps as drupal_get_form, i.e. the code below and the user login
block displays but there is a bunch of stuff missing from it so it
doesn't actually submit.
Am I making this harder than I need to for what I'm trying to achieve?
Regards,
Anthony.
$form_state = array();
$form = drupal_retrieve_form('user_login_block', $form_state);
drupal_prepare_form('user_login_block', $form, $form_state);
$block['content'] = drupal_render_form('user_login_block', $form);

You don't need to start from scratch but you do need to code using
hook_form_alter to add the appropriate form elements and also a
hook_user to capture the user operations and operate on the
appropriately.
