I'd read the wiki page previously; it doesn't explain the details of 
what I'm looking for. It indicates that "Today, all necessary modules 
loading is handled automatically by udev..." but I haven't been able to 
find out *how* module loading is done by udev.

I'd read that as well, but that's a last resort. I don't know why 
snd_seq_midi isn't loaded automatically anymore and so don't know if 
it's intentional or if it's a bug.
