fsck's are not done on every reboot.  They are done every X mountings of the 
filesystem (I think the default is 8 or 10).  The fsck entry in /etc/fstab just 
specifies the order that partitions should be fsck'd on reboot and is very 
important if the partitions are uncleanly unmounted (e.g. hard power reboot). 
If you are using a journaled filesystem (ext3, jfs, xfs, ReiserFS, etc...), then 
fsck's won't take nearly as long as they would under non-journaled filesystems 
(ext2).
