Well, I don't think you're a moron.  But then, I don't think I'm a moron 
either, so maybe my judgement is impaired!

Yes, yes, yes, that's exactly what I did (unless I'm very much mistaken).
I'm sorry if my long posts cause confusion.
Here's a transcript - nothing omitted except mechanics of editing:

The line with eth1 is having no effect whatsoever.  The line with wlan0 
is being inserted by the command modprobe hostap_pci, nothing else.

Well, if you say so.
But I can rename interfaces (as root) without using udev, so if I can I 
presume a systems program can too:
