The "ALSA sequencer" is the sequencer (ie: high level) interface to MIDI
interfaces, either real external ports or ports offered by software
packages. 

On FC3 that particular kernel module is not autoloaded, the workaround
is to enable the alsasound startup script:
  /sbin/chkconfig alsasound on

A reboot should load the ALSA sequencer kernel module and qjackctl
should not complain anymore.
