1GB D9GMH modules, what sort of kit's are we talking here?

Dozens if not hundreds of different models.
Will take too long to describe and doesn't really belong in this thread. You can use RAM-list as a tentative reference: http://ramlist.i4memory.com/ddr2/

Early 6400 Ballistix, what's the identifier to tell if early or later?7

2GB modules with PN ending with -16FE5 used D9JKH. Later they've switched to something else, which I am not sure will do 550+ CL5.
