No. It will not load arbitrary files, but _only_ files that end in
".ko". I've encountered this before, and therefore I always simply
follow a make installkernel.debug by a script like:

  #!/bin/sh
  kernpath=/boot/kernel
  for i in ${kernpath}/*.debug; do mv $i `echo $i | sed s/\.debug$//`; done
  rm -fv ${kernpath}/linker.hints
  kldxref -v ${kernpath}

This is simply because I almost never keep a copy of /usr/obj after
installing, and it can be handy to debug later. I assume that all
debugging info is simply ignore by the boot and kernel module loaders,
but it can later be used by kgdb.
