Yes, unfortunately it doesn't handle fragments at all.  I looked
at the card specs when devising the interface, to make sure that 
the new interface will be able to handle various chips.  I haven't
changed the 3com driver though, as I didn't want to spend time 
trying to figure out what the chip actually does vs what the manual
says it does.
