embarrassing to reply to one's own posting ... the lack of success on 
the Mac Pro and the Dell Precision was "pilot error" - I installed the 
i386 kernel on x86_64 machines !

After fixing this, I find that the new kernel works well on the Dell. I 
didn't have time to test the Mac Pro, but the boot messages looked ok on 
a quick check.

So - no reason for bug reports.
