KERNEL:
[...]
#device          pcm
[...]

loader.conf:
[...]
snd_csa_load="YES"
[...]

dmesg:
[...]
csa0: <CS4280/CS4614/CS4622/CS4624/CS4630> mem 0x50000000-0x500fffff,0x50100000-0x50100fff irq 7 at device 6.0 on pci0
csa: card is Thinkpad 600X/A20/T20
pcm0: <CS461x PCM Audio> on csa0
pcm0: <Cirrus Logic CS4297A AC97 Codec>
[...]

rc.suspend:
[...]
logger -t apmd suspend at `date +'%Y%m%d %H:%M:%S'`
kldunload snd_csa
sync && sync && sync
[...]

rc.resume:
[...]
logger -t apmd resumed at `date +'%Y%m%d %H:%M:%S'`
kldload snd_csa
mixer vol 85 pcm 85
[...]

and works fine for me :)))
