I fake background fsck with a 108G drive.  I have it not auto fsck on boot, 
and added:

(sleep 30; fsck -p /dev/wd1a && mount /export && mount -a ) &

to the end of my /etc/rc.local.  That mount is not nessesary for 
normal use, of course.  /etc/fstab for that mount has a 6th field of 
"0".  On an unclean boot, it fscks all of the other partitions, then 
errors (but continues with regular boot) on /export.
