Burning into NOR should not be a problem. Can you reinstall a 
bootldr.small? That might be a useful test. It would indicate if the 
problem is in bootldr.fast boot or burning it into NOR.

I know I am banging on about this but if the same code builds and runs 
for gcc 2.95 and fails for 3.3 that might suggest that there is a deeper 
problem. Can I suggest that you tgz your code and place it somewhere 
public or even email it. I'll download it, build it under 2.95 and send 
back the results.
