Not answering the question but...
Have you considered not using frames? I seem to remember iframes were only compatible with internet explorer.
Also frames can be a pain for search engine listing, people who find framed content come in on the frame not the site so can not easily navigate etc.
Not so great for some mobile browsers either.
I am managing get by with using tables and .php includes. It might not be the answer for you, and is certainly not the answer to your question, but may be worth considering.
Perhaps if you could post a chunk of sample code or a link to a test page one of us woudl be able to help more.

UPDATE:
Thinking about this the only way I can see to do it with iframe is to have a different page containing the iframe for each menu item, as you need to specify the target url for the frame on the page being called not in the menu link. Obvioulsy each url in the separate iframes can call a different section of the document in the frame using the name attribute in the anchor.
That assumes of course that you control the document being framed so that you can add the anchors and know that they will not change.
Not hard to do, a copy and paste job, but it does requre a few more files. SHould not need much more space though as all graphics are shared and the framed document is common to all.
