That was the problem, I had located the data sheet for the part and 
figured it out and can now program the external flash fine.

I don't know much about programming flash yet so I don't have any 
ideas.  I have looked at the documentation for the UC3F FLASH module, 
and it is different from the way the AMD part works in that it is 
register based.  I may try to sort out how the flash stuff works and 
add support for it.  If you want to send me a few ideas for cleaning 
things up I'll look at them.

Patches will come in about a week, I have to finish a first version of 
this project then I'll clean things up and check that it builds on 
Linux.  I'm not sure I'll be able to test it, though, since I don't 
have a local Linux box.
