Hmmm, weird.

Let's see if you have the device files:
  ls -l /dev/snd/midi*
  ls -l /dev/seq*

Or we could try to trace kmidimon to actually see what's failing. To do
that do:

  strace kmidimon &> trace.text

and then examine trace.text with an editor, I imagine there is something
wrong with /dev, a file missing or something like that.
