It shows that there is more then one way to skin a cat.

That uses a a true ISP chip, and programs it via its SPI port.

So this doesn't help the OP, who wants to program the external Flash of a non-ISP 80C51.

Other than that, it looks like essentially the same idea as the Atmel app note (ie, adding a 2nd processor to do the programming): http://www.8052.com/forum/read.phtml?id=135353
