Well, wss(4) recording doesn't work here in 4.99.26.  audiorecord
ends up getting a EINVAL in the setup phase and bails out.
cat(1)ing /dev/sound acts about like a blocking /dev/null.
vmstat -i shows the device interrupting while trying
to record.

There have been some seemingly significant modifications
between 2.x and 3.x in the CVS logs.  It's hard
(well, harder than I want to work on this now)
to track as there are like 3-7 files that wss(4) comprises of.

Good luck.  Also, ISA hardware isn't fun anymore.
