TP 600X 2645-EYG

RELENG4

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

rc.resume:
 sync && sync && sync
+kldload snd_csa
 exit 0


and works fine :)  



btw: i had some panics/lockdowns with pcmcia power down added to rc.*
(to suspend with AC) 

best regards
