It looks to me like the lines that were added in 2.2.18 just prior to the
Insert root
floppy prompt, which check for initrd, were reverted sometime before 2.4.3.
I don't
have a clue how to easily find out what revision the revert took place in,
but I'm thinking
this might be the cause of the no-response woes. ('Cause they probably had a
similar problem
and later fixed it by reverting.) I would normally look for something after
the wait_for_keypress
to have been changed, but I'm thinking maybe if the floppy doesn't get into
the right state before
the wait, the wait could last a long time.
Here are other possibilities of powerpc kernel changes in 2.2.18 related to
floppy,
boot, etc.
