Why would knoppix come with the Rosegarden sequencer and playmidi, if it doesn't configure your midi port for you?

My soundcard's WAV out works fine, but the MIDI part doesn't seem to get configured since /dev/sequencer isn't setup. (yes my soundcard ALS100 is on the list of supported cards for the OSS driver)

The soundcore module seems to be installed, so surely there should be a way to get midi working without a harddrive install?????
