Well, for a start, you need the appropriate tools:
happy-idiot-talk:/usr/ports:% make search key=ext2
Port: e2fsprogs-1.27
Path: /usr/ports/sysutils/e2fsprogs
Info: A set of utilities and library to manipulate an ext2 filesystem
Maint: ports@FreeBSD.org
Index: sysutils
B-deps: gmake-3.79.1_3
R-deps:
Port: fsck_ext2fs-2.8
Path: /usr/ports/sysutils/fsck_ext2fs
Info: Ext2fs filesystem consistency check and interactive repair
Maint: roman@xpert.com
Index: sysutils

You'll have to experiment to find out which of the fsck programs from
those packages suits you best.
If you want to automatically fsck(8) ext2 partitions on boot-up in the
same manner as the system checks UFS partitions, then you're probably
going to have to write some custom startup scripts.
You might be able to run something out of rc.early (see rc(8)), but
remember at the point that script gets run, only the root filesystem
is available and you're pretty much limited to the statically linked
binaries in /sbin
Otherwise, you probably need to mark any ext2 partitions in fstab as
'noauto' so the system doesn't try to mount them with the rest of the
partitions, and then write yourself a mount-ext2.sh script to go in
/usr/local/etc/rc.d which will run fsck_ext2fs and mount the ext2
partitions on startup, and similarly unmount them on closedown.
Cheers,
Matthew
