Sure, ext3 is just ext2 with journalling added. Unmount the partition
and mount it as ext2 instead.

but would this save any space on the drive?

No. But, once you've mounted it as ext2, you can use the tune2fs tool to turn
off and delete the journal. Once you do that, you reclaim the journal's space on
the drive.

If it's space you want to reclaim, it's far more interesting (most
certainly with the 100+ gig drives that are coming with PC's nowadays)
to reduce the size of the reserved blocks on your partition.
The default of 5% that is reserved for the root user (so that logs
will continue to be written, and root can save the day when normal
users experience 'disk full') is just overdoing it. Note, that 5% of a
100 GB disk is 5 GB of space that you won't be able to use. Bring it
down to 1% (only integer numbers are allowed here) and you suddenly
have 4 GB of additional space (and root still has 1 GB reserve).

Example command for a partition on '/dev/hda1' :

tune2fs -m 1 /dev/hda1

and you don't even need to umount the partition to run it.

PS: a percentage of zero is allowed too if you don't care about root's
future problems (well you are root anyway, but hey, who isn't a
little schyzofrenic here in aols).

Cheers, Eric
