Just an update ... I now have it working ... yay !!

The main (and possibly the *only*) culprit was that SYSBOOT[8] (which selects
8/16bit mode) was being incorrectly influenced by a hardware fault.

I have pulled quite a few patches from various places, some of which might
not be required.  Now I have a working base, I'll work out what is needed
on top of Tom's original patch set.

Thanks for everyone's support.
