I ran into similar problems last October when working with options in
4.2 BSD.  I believe I had to patch both the fragmentation and reassenbly
routines to get things running.  The most common problem I found was
references to the size of a 'standard' IP header [sizeof(ipasfrag)],
instead of references to the size of the current datagram's header
[ip->ip_hl*4].  If you need more specifics, drop me a note and I'll look
them up.
