Great! Do you still get all those warnings about BoundedListTemplate? I would
expect so, since templates in C++ are a little strange.

I had found this comment in vm/templates/link.make

# Rule that links Self is in Dependencies (created by makeFileList).
# ${AOUT}: *.o
#       ${LD} -o $@ *.o ${PATCHED_OBJS} ${LIBS}
# files: *.o

which I assume means the bin/shell/makeFilesLists script...

Hmmm... I don't know what these "trapdoors" and "registerLocator" are all about.
The Sparc versions of these seem to be empty implementations, so it probably
is some PPC specific thing. Of course, it might just make your step 10 (walking
the stack) easier.

Note that if you complete all your planned steps and get to the point where you
might want to read in a Snapshot file, this is the first "little endian"
implementation of Self and you might have a few complications with this.

Good luck!
