pdftex has no means to accept a mode and pass it to mktexpk, so mktexpk
will first try its default mode. If that does not match the bdpi,
it falls back to a list of fallback modes with the right bdpi. This
only works for a few resolutions:

  if test -z "$MODE" || test "x$MODE" = xdefault; then
    case "$BDPI" in
      85) MODE=sun;;
     100) MODE=nextscrn;;
     180) MODE=toshiba;;
     300) MODE=cx;;
     400) MODE=nexthi;;
     600) MODE=ljfour;;
    1270) MODE=linoone;;
       *) echo "$progname: Can't guess mode for $BDPI dpi devices." >&2
          echo "$progname: Use a config file, or update me." >&2
          exit 1

There is no easy solution for this other than fixing pdftex, I think.
So, I hereby ask if someone wants to implement this. pdftex should not
only read pk_resolution from pdftex.cfg, but also some variable for the
metafont mode and then pass this to mktexpk (instead of "/"). Will
anybody implement this?
