I wrote up a quick draft (see below).

A New Internet-Draft is available from the on-line Internet-Drafts directories.

        Title           : GRE Tunnel Fragmentation
        Author          : Fred L. Templin
	Filename        : draft-templin-intarea-grefrag-00.txt

Abstract:
   GRE tunnels use IPv4 or IPv6 fragmentation of the delivery packet
   when the delivery packet exceeds the tunnel MTU, or when otherwise
   necessary.  This can cause problems when unmitigated IPv4
   fragemntation ensues, or when middleboxes drop IPv6 fragments
   unconditionally.  This document proposes GRE tunnel fragmentation
   which avoids these pitfalls..
