Well, so far I have found ipt_DF from http://mordor.strace.net/iptables/,
which seems to do the job. The DF flag is indeed stripped and no
more ssh-sessions crash :)

But I was wondering, do you have the functionality of a specific
officially included iptables module in mind ? It's quite a pain to
compile libipt_DF.so on every machine..
