The root file system is ext3. I could use resize2fs to shrink it, but it
won't if it's mounted, and I cannot umount the root file system on a
running system.

My solution was to boot the installation CD in rescue mode. I somehow
managed to get to the partition disks part of the installation which I
used to resize the root system. It gave some error message, but after
rebooting, the fs was the size I wanted, but the volume had not changed
in size. The LVM utility sorted that out though.

So I've done what I needed to do, but I feel there should be a cleaner
way. Maybe a live CD boot would have helped. (Oh, booting into recovery
mode didn't help. I could umount /, but then the resize2fs utility was
not available!)
