In case I was unclear, if DDB is not set, the symbol table would be
kept in pageable memory, not wired memory.  Would you really miss the
swap space?

This would take care of the problem of booting from a kernel other
than "netbsd", but things would still fail if you move the kernel
around.  Keeping the symbol table in swap space is certainly more
robust, albeit more costly.
