OK.  I never tried that.  Ragge did mention at one point that b/40
would help "avoid some [of] the problems", but he didn't say precisely
which ones.  He did definitely say, on 12/6/98:

# It seems as your boot loader is too old; it doesn't move itself up to
# a secure address and gets overwritten by the kernel. Try a newer
# loader.

I wouldn't have thought that loading the symbol table would cause the
old loader to relocate itself.  That's too much magic for me...

Cheers,
