I can't ;) this was an explicit requirement.

As for the devkit8000 boot problem, I have BSS set up close to the top
of the RAM. Probably that's the reason I don't see any problems.

Unfortunately, I can't recall why I had moved BSS... It clashed with
something but I don't remember the details.

Regards, Ilya.
