so go ahead and add everything that i did before to the list, plus
tack on changing yaboot.conf back to its original state prior to this
whole mess (which is basically to remove all of the open firmware
paths):
# ybin options
boot=/dev/hdb9
macos=/dev/hda
so that ybin would seek out the proper paths on its own.
Phew!
Big thanks to Keary for getting me on the right path, and to Google
for showing me the way. <<grin>>.
Now the only question that remains is: was it installing mac-on-linux
that caused this problem in the first place?
