When the rescue prog comes up, tell it not to try to mount your   
system, then you can run an fsck there just fine. Otherwise, umount / 
mnt/sysimage/{proc,sys,some other stuff}, then you can umount /mnt/ 
sysimage. Automatic checks at system boot time are generally   
triggered off of the presence of /.autofsck, which is created every   
boot, and deleted on every clean shutdown. Thus if the file is there   
on startup, we assume shutdown wasn't clean. 

So you can either create that file while booted in the rescue   
environment, or create it booted into your actual system and make it   
immutable or something to prevent it getting removed on shutdown   
(just remember to undo that afterwards).
