I noticed on 2.6.16-rc4 that my MPU-401 wasn't functional, due to a

Thanks, I applied it to ALSA CVS tree, too.
The patch Adam sent fixes the ".remove not called" issue. It _also_
fixes the OOPS in snd_timer_free() I sent along, so that one wasn't
independent. During testing, I uncovered one more bug though.
After using aplaymidi (to test cs4236 mpu401), which pulls in
snd-seq-oss, modprobe -r snd-cs4236 tells me:
"ALSA sound/core/device.c:106: device free eee4e000 (from f099153d), not
found"
That then stays until reboot, with a different device address each time.
f099153d is snd_opl3_free_seq_oss() here. For now I've stuck a
dump_stack() in there, which treats me to:

I'll try and see if I can find anything later, but if you could, please
beat me to it. I'm not even quite sure what that oss sequencer thing is...
