I have a pretty old Sound Blaster 16 card from Vibra. It's a good old
NON-PNP ISA card. It works just fine except for the need to manually
configure symlinks inside /dev and to ignore some strange diagnostics
on boot while using new DEVFS. Here's a dmesg extract:

=========
Those symlinks audio, dsp & mixer are configured to be created at boot-time
in rc.devfs (by me).
And that's a kernel config extract:

=========
>Description:
All those sequencer devices are just weird both by spoiling /dev and
highlighting at boot time.
/dev/audio, /dev/dsp & /dev/mixer must be created manually.
>How-To-Repeat:
>Fix:
Create symlinks. Don't care about sequencers, unknown <PNP_ID> and
other error messages in dmesg.
Or dig /sys/dev/sound in an unknown to me direction.
