Audio on Ultra 1?

[Torfinn Ingolfsen]

Hello,

I tried this patch:
http://www.kr.freebsd.org/~yongari/cs4231.freebsd.diff

on my Ultra 1E (which is running 5.3-RC1). I have made world and built
a kernel on this machine yesterday, so I know that it used to work.
But after applying the patch, make builkernel failed:

In file included from /usr/src/sys/dev/sound/pcm/sound.h:93,
                 from /usr/src/sys/dev/sound/sbus/cs4231.c:53:
/usr/src/sys/dev/sound/pcm/channel.h:69:24: channel_if.h: No such file
or directory/usr/src/sys/dev/sound/sbus/cs4231.c:60:22: mixer_if.h: No
such file or directory mkdep: compile failed

Is this patch supposed to work on 5.3?
