Måns, I think you need to read the question more clearly before answering.
This is a snapshot LV, so it is always read-only.  The ext3 filesystem is
"unclean" because it was snapshotted without the VFS lockfs patch in place,
so the ext3 filesystem doesn't know it needs to flush the journal.

Anthony, the patch you are looking for is in the LVM CVS at sistina.
