Actually, this was all highly un-necessary voodoo....

My biggest problem was that I had enabled the serial-port debug code in the
2nd-stage bootloader, which was causing all the havoc by making the stack
grow up rather than down when it attempted to preserve the two registers it
trashed... D'oh!  As you might imagine, that doesn't work so well when you
set the initial stack pointer to just below the bootinfo page.

Just pretend you didn't see any of the patches I sent ;)... I'll report here
again if I find more/other problems.

Sorry for all the noise,
