My testing used the parted package shipped with the Ubuntu 10.04 beta 2 
release.  My understanding is that this beta distribution uses a version 
of parted that includes the BLKPG patch.  I am basing this on an excerpt 
from
http://changelogs.ubuntu.com/changelogs/pool/main/p/parted/parted_2.2-5ubuntu4/changelog

parted (2.2-1ubuntu4) lucid; urgency=low

  * put-back-BLKPG.patch: Upstream removed the code using the new
    BLKPG ioctls instead of the old BLKRRPART ioctl to update the
    in-kernel partition table.  This patch reverses that change.
  * error-check-BLKPG.patch: Add error checking to the BLKPG code to
    fix up the old BLKPG code to satisfy upstream.  (LP: #540940)
  * Refresh quilt patches.



Using the Ubuntu Live CD was the fastest way for me to test this patch 
to parted.

If you wish I can also try to recreate the problem using a plain vanilla 
parted-2.2 with the BLKPG patch applied.
