No. And you meant 256MB.
But c3k and b2k both supported the same DIMMs originally (128 and 256MB
DIMMS). Minimum mem possible was thus 128MB and I thought 256MB was
the minimum shipped with each box.

Sorry - I don't know why reverting that diff matters.

head64.S only runs wide mode on PA20 HW.
No need for any PA11 or narrow mode code.
Look in the Makefile and see when head64.o is linked in.
Then you'll *SMACK* yourself on the forehead and say "DOH!" :^)

AFAIK, it's just telling the assembler where to expect global symbols.
