What version of e2fsprogs were you testing with?  I've just tested
using the latest version of e2fsprogs, and it works just fine.  In the
test below, I corrupt /etc/blkid.tab by swapping /dev/hda and
/dev/hdc.  This might correspond with might happen after disks get
switched around.  I run fsck in debugging mode to make sure it gets
the correct devices, despite the corrupted /etc/blkid.tab file.  As
you can see, it works fine:

# sed -e 's/hda/hdz/g' -e 's/hdc/hda/g' -e 's/hdz/hdc/' -e 's/0x03/0xf3/' -e s'/0x16/0x03/' -e 's/0xf3/0x16/' /etc/blkid.tab  > /tmp/blkid.tab.broken

# cp /tmp/blkid.tab.broken /etc/blkid.tab

# fsck -AVN -a
fsck 1.35 (28-Feb-2004)
Checking all file systems.
[/sbin/fsck.ext3 (1) -- /] fsck.ext3 -a /dev/hda1
[/sbin/fsck.ext3 (1) -- /usr] fsck.ext3 -a /dev/hda3
[/sbin/fsck.ext3 (1) -- /debian] fsck.ext3 -a /dev/hda5

# e2label /dev/hda1
root

# e2label /dev/hda3
usr

# e2label /dev/hda5
Debian

The only thing I can think of is that you might have been using an
older version of e2fsprogs that was buggy....
