Almost all chips are using the same values in the initvals - the
exceptions seem to be the ones that have had ETSI compliance fix
attempts already. I'm pretty sure the new values (if adjusted for
different bands) would be fully compatible.

I know. What I meant is that in case the EEPROM does not have any
values, we can make it use reasonable fixed defaults, thus overriding
the values from the initvals.
