Has anyone customised the payment-processing page before?

The one that by default just has the "Your order is being processed" message, and does not use the template design of the rest of the site, with a coloured top border.

It uses body class payment-wait, and I've tried calling my customer/head.tpl template from inside /payments/iframe_init.tpl, but it doesn't seem to have access to the main variables from the rest of the site.

For example it doesn't have access to my quicklinks/speedbar links.
I've turned on the debugging console, but it doesn't work on the payments page.

Any ideas for (at a minimum) passing the speed_bar variable to the payments module?

We are using an iframe-based payment method hosted by the payment gateway, so that we don't have to collect the data ourselves, and do the additional PCI compliance checks. It's being developed by xcart (still testing) and unfortunately the card details have to be entered on the separate payment page, instead of the earlier one.
