It's coming out at about 19k for me without networking - (and thats with
the CLibrary in ROM). I'm hoping to get this down a bit but don't think
I'll be able to do much better.

So I'd like the contiki code to be in two roms and the clibrary in
another two. Leaving most of normal ram free.

The trouble is getting calling between different ROMS to work. I don't
think my original posting was clear. I need to call between several
different roms and each rom needs to call the OS. What is the correct
way of making sure the OS reselects my ROM? I've tried poking &f4 but
the OS seems to ignore this and returns back into the ROM I've got
selected as the language.

Cheers
