It turns out that adding the oss modules to the blacklist isn't
enough; you also have to take them out of /etc/modules and
/etc/modules<kernel version information>.  But I am now booting with
no oss modules that I know about, including not the ones you mention.

A nice side effect of all the reboots that it took to figure that out
is that sound now comes up configured and enabled without my runing
alsaconf and stuff.

However, I still don't have MIDI.

The only sound-related error message I see when I boot up is:

root at serpent:/var/log# grep snd_seq syslog
Jan 11 12:08:23 serpent modprobe: FATAL: Error inserting snd_seq_oss (/lib/modules/2.6.14-2-686/kernel/sound/core/seq/oss/snd-seq-oss.ko): Device or resource busy 

This suggests to me that the modutils files written by something or
other (certainly not me) are confused about what order to load things

My (clearly not educated enough) guess would be that snd-seq-oss 
would have something to do with the oss emulation, which wouldn't be
what aplaymidi would be using to play MIDI files, but of course, if
my system is confused about this, who knows what else it might be
confused about?

So does anyone want to explain what this error message means, or make
a new guess about why my system doesn't play MIDI files?
