(necro)dropping a quick note:

It seems that the ATmega8/L got a direct replacement that is cheaper and easier to find.
In order to optimize the manufacturing process and to further reduce current
consumption, an optimized version of ATmega8 has been introduced.
The ATmega8A is a functionally identical, drop-in replacement for the ATmega8.

Nice find!
Looks like they have streamlined it, so we don't need the low power "L" version anymore. The 8A supports our needed low voltage of 3V.
Maybe need to change a bit in the Makefile (target), but then we have a cheaper replacement chip (2,20€ → 1,80€ reichelt germany store).

Theoretically no changes are needed, since it is a drop-in replacement.
I already have ordered one, so I'll test it~
