from fstab(5) on my 2.0.2_STABLE machine:  (emphasis added)

	The sixth field, (fs_passno), is used by the fsck(8)
	program to determine the order in which filesystem
	checks are done at reboot time.  The root filesystem
	should be specified with a fs_passno of 1, and other
	filesystems should have a fs_passno of 2.

	Filesystems within a drive will be checked sequentially,

	but filesystems on different drives will be checked at
	the same time to use parallelism available in the
	hardware.  If the sixth field is not present or zero, a
	value of zero is returned and fsck(8) will assume that
	the filesystem does not need to be checked.

is the man page incorrect?
