2.1.129, cs4232, /dev/sequencer: No such device

Hi, I've just upgraded to 2.1.129 from 2.0.36, and I'm finding a few things a little strange. I can't seem to play midi files because the sequencer device isn't set up properly. Any help is welcome (including messages telling me I'm too thick to live, IF they also tell me what I'm doing wrong).

My sound device is a WaveX 32 Pro. ie a cs4237b pnp isa card.
