Ok, so no luck there.

That would be great. Could you find out when that firmware was released?
In general I'd like to get the oldest firmware on it that you possibly can.
Did any software come with the shuffle? Maybe a it contains a reset utility
that contains old firmware?

I've found some comment in a forum in late 2006:

If that firmware FIXED the shuffle's behavior to what we see today, and 
it didn't change from one vaild behavior (the one from 1g shuffle) to
another (todays), then we might simply solve the issue by adding new model 
strings to gnupod and change the behavior of mktunes accordingly.

Does apple publish something like a changelog for their firmware updates?
