 so this explains the fault.  there's nothing mapped there.

 FWIW, this number came from the screenshots.  eg:
 
        db{0}> bt
        config_cfdriver_lookup(c0bc2bfd, ...)
 
 this number seems corrupted.  gcscide_cd+0x1d is 1 byte after the
 start of gcscide_cd->cd_attrs.  it *should* be a pointer to the
 string "esm" i thought.  what does this print?
 
  db> x/s 0xc0bc2bfd
 
 i'd expect random garbage.  but not "esm".
 
 but i'm not really that great with i386 asm, nor autoconf... any
 one else have a clue here?
