Thanks a lot! This made it work:
writer.writeAttribute("defer", Boolean.TRUE, null);
In my code I had
writer.writeAttribute("defer", "true", null);
which didn't work...
Now it works in Firefox without any JavaScript errors. In IE I get a strange
error located inside the dojo Javascript sources. So I have to dig deeper in
the dojo sources. But anyway your hint brought me a great step further!

Roughly speaking, yes, though it's a lot more complicated than that.

No, it's actually more clever than that - as long as you write out the
script element using ResponseWriter.startElement. My memory's gotten
a little fuzy on the details - you may
also need to call writeAttribute("defer", Boolean.TRUE, null). But,
at any rate, the script
is blocked for execution in the iframe, then executed in the main page.
When I get the chance to rewrite the code to use XMLHttp instead of an iframe,
this gets a bit easier in some ways (a bit harder in others).
