So which TAHI test was this? Have they tracked down a commit that
caused this to break?

Hmmm, I would take a look at this commit:
commit b5c15fc004ac83b7ad280acbe0fd4bbed7e2c8d4
Author: Herbert Xu <herbert@gondor.apana.org.au>
Date: Thu Feb 14 23:49:37 2008 -0800
[IPV6]: Fix reversed local_df test in ip6_fragment
I managed to reverse the local_df test when forward-porting this
patch so it actually makes things worse by never fragmenting at
all.
Thanks to David Stevens for testing and reporting this bug.
Bill Fink pointed out that the local_df setting is also the wrong
way around.

Where's the expected fragments? See below where after the TOOBIG the
next ping6 will generate them:

Maybe check the interface stats for IPv6 fragments and see why it failed:
# cat /proc/net/dev_snmp6/eth0 | grep -i frag
It would take me at least a day to get my TAHI box setup to test the
latest net-next kernel to see if this is still broken upstream.
