So, it turns out that the ATMega128 seems to be quite susceptible
to the EEPROM address 0 correction bug which has plagued
Atmel in the past.  Atmel just hasn't acknowledged it, or deemed
it fit information to put into their errata.

This was my first real foray into Atmel-land, and I gotta say, I don't
like what I've seen.  The programmer (JTAGICE mk II) that I
started out with has gone stupid on me (it still communicates, but
I can't get it to actually work with a chip)(I think it may be that
crappy under-robust ribbon cable they give you with it), my company
spent many hours of engineering time and customer goodwill
hunting down a problem which SHOULD be in the errata but isn't,
and which Atmel didn't tell me about when I asked them, specifically,
whether it might be an issue, and when I finally DID get a programmer
working, I'm finding that programming multiple boards seems to
require reconnecting to the programmer between each one.

Add in their reputation (as I've heard) for discontinuing parts at an
above-average rate, for supply chain issues, and the news Russell
posted, and I think I'll stick with Microchip.

Of course, my employer has thrown THEIR hat in Atmel's ring...
