Thanks for answering, Clemens. Comments are inline.

It looks like the driver does not care about that.

It can be loaded but is not loaded by default as mtpav does not work if any other parport driver is
loaded.

Ok, this is where the default message: "Motu MidiTimePiece on parallel port irq: %d ioport: 0x%lx\n" is written from. So there is no error too.

BTW: lsmod |grep snd_mtpav shows, that it is using snd_rawmidi...

snd_mtpav              16384  0
snd_rawmidi            32768  2 snd_mtpav,snd_seq_midi
snd                    81920  5 snd_mtpav,snd_timer,snd_seq,snd_rawmidi,snd_seq_device

Was there a recent api change? More and more it looks like there is a problem with registering the driver / the port to the ALSA system.
