[LAU] nforce (intel8x0) midi

I've just found that I have a game port midi adapter, so while I wait for my USB-midi device to arrive I thought I'd give it a try. However, I cannot for the life of me find any information on how I go about enabling midi on my nforce mobo. A post on the alsa mailing list said that adding the option mpu_port=330x0 to the snd-intel8x0 module worked, but that wasn't specifically for an nforce, and my version of snd-intel8x0 doesn't actually have any mpu options! I've loaded every module I could find called snd*midi or snd*seq, and still the only output I get from aconnect -io is: client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' client 128: 'TiMidity' [type=user] 0 'TiMidity port 0 ' 1 'TiMidity port 1 ' 2 'TiMidity port 2 ' 3 'TiMidity port 3 ' Any ideas? Thanks Simon
