AC97 on FBSD 5.1p8 on Clevo Laptop

I have a Clevo Laptop (don't ask why) with an AC97 sound card that I 
have had running on 4.8, but cannot be accessed under 5.1 using devfs.

The problem is noticable when starting KDE, which generates the mesage 
about /dev/dsp not being accesible. Which is hardly surprising, since 
there isn't one.

I've never worked out which device should be created for AC97, but guess 
that it isn't /dev/pcm0, since there is the appropriate device line in 
the kernel config, but the device doesn't get created at boot time.

Question is which device should I be putting in the kernel config and 
accessing in /dev to make the sound card accessible. (Assuming it is 
compatible with 5.1.)

Any comments gratefully received.
