Greg - I used LVM a bit this week to fix a bug, and the snapshots were
working, at least as far as being able to create / mount / umount them.
I don't know what flavor of LVM or XFS is in the SuSE kernel you have...
but this is working for me with current CVS:
pvcreate /dev/sda2
vgcreate volgroup2 /dev/sda2
lvcreate -L500 -nlogicalvol2 volgroup2
mkfs.xfs -f -q /dev/volgroup2/logicalvol2
mount /dev/volgroup2/logicalvol2 /mnt/lvmtest/
xfs_freeze -f /mnt/lvmtest/
lvcreate -L500M -s -n snapshot2 /dev/volgroup2/logicalvol2
xfs_freeze -u /mnt/lvmtest/
