Yep, we noticed after 1.2.0 had been rolled out that we need to update
the documentation.  This has been done, so 1.2.1 has been ``fixed'' in
that respect.

That's exactly our recommended workaround for the time being, until we
moved avr-libc to a per-device library structure (which will then at
least be called avr-libc 1.4.x, perhaps even 2.x.x).  The existing
eeprom.S file should work fine on the currently unsupported AVRs,
provided it has been compiled with the appropriate -mmcu option.

Never trust an operating system you don't have sources for. ;-)
