Just noticed that the old home page was index.php too. So this hasn't changed, and the content hasn't changed much on the home page, just the coding structure really. What else could cause the slump in the home page rankings?

If you wish to retain any of the rankings that you had previously achieved you should consider using a 301 redirect from the old URLs to the new ones. This tells Google that you have permanently moved the page and any inbound link juice and PR should eventually move to the new page. If you've changed other aspects of the page, such as meta tags and content on those pages, I wouldn't expect to regain those exact positions.
If you just let things sit it could take a good deal of time and work to regain lost position.

Just some daft gotchas that might have gotcha if you haven't been careful.
Is ther any chance the googlebot has got into /old_website . Check your logs. If it has I guess it could penalise you for dupe content.
Have you submitted a siteindex.xml to Google? If you have, you have remembered to change this haven't you?
If you have changed from tables to divs using a WYSIWYG design prog you could have completely changed the order within your pages without realising it. This may have changed the balance between density and prominence for your target terms. Have you tried a tool like gorank's keyword density analyser? You could point it at your new index.php and the old one lurking in /old_website and see what that tells you.
FWIW I reworked one of my secondary sites changing it to php from static html and got better rankings as a result. I didn't do any 301 redirects, just thought I had little to lose with it so could wait for it to find its level.
I'm working on my main site now and to be frank I'm scared stiff I'm going to do something wrong when I change over.

I'm pretty sure Google won't forget about pages they have indexed as people still notice GoogleBot trying to access pages that they dropped years ago. Regardless if Google still has the pages indexed or not he should use the 301 redirect. Inbound links are probably still pointing to those old URLs and only a 301 will fix this. Unless of course you can go to each and every page that links to you and ask them to update the link;)
