yep.  that was what i meant.  kinda like pmap(1) that prints the
process's memory map.  i like that one, too, but perhaps i'm partial
to it because i wrote it.  :)

i once wrote a perl script (i don't even remember why) that takes
/var/run/dmesg.boot and prints this:

% ~/src/perl/devtree /var/run/dmesg.boot
cpu0 at mainbus0
pnpbios0 at mainbus0
  pckbc1 at pnpbios0 index 7 (PNP0303)
    pckbd0 at pckbc1 (kbd slot)
      wskbd0 at pckbd0
    pms0 at pckbc1 (aux slot)
      wsmouse0 at pms0 mux 0
  pckbc2 at pnpbios0 index 8 (PNP0F13)
  fdc1 at pnpbios0 index 11 (PNP0700)
  com0 at pnpbios0 index 14 (PNP0501)
pci0 at mainbus0 bus 0
  pchb0 at pci0 dev 0 function 0
    agp0 at pchb0
  ppb0 at pci0 dev 1 function 0
...

or this:

% ~/src/perl/devtree -v /var/run/dmesg.boot
cpu0 at mainbus0: (uniprocessor)
pnpbios0 at mainbus0: nodes 14, max len 262
  pckbc1 at pnpbios0 index 7 (PNP0303): kbd port
    pckbd0 at pckbc1 (kbd slot)
      wskbd0 at pckbd0: console keyboard
    pms0 at pckbc1 (aux slot)
      wsmouse0 at pms0 mux 0
  pckbc2 at pnpbios0 index 8 (PNP0F13): aux port
  fdc1 at pnpbios0 index 11 (PNP0700)
  com0 at pnpbios0 index 14 (PNP0501)
pci0 at mainbus0 bus 0: configuration mode 1
  pchb0 at pci0 dev 0 function 0
...

like i said, i don't remember why i wrote it now, nor what i would use
it for...
