If you do not like that, why do you make it that way?

It is reasonable to expect some delay, if you first load the iframe with 
the default page, and then only when the total is loaded start changing 
the iframe. There is no reason to wait for the page to be loaded to start 
testing the hash.

But as you show, the whole setup stinks, because it "prefers" noscript,
while most browsers are script enabled, so noscript should be the 
fallback.

If you must, perhaps:

<iframe id='myIframe' style='display:none;'></frame>
<noscript><iframe src='blah.htm'></frame></noscript>

and have script fill the source of the first iframe and change the 
display?
