Debian 3.1 (the last release to support m68k) supported
Amiga, Atari, Mac and VME.

These were also the most popular m68k platforms at about
10 years ago. [1]

But what about the rest?

As long as a platform has at one or more users it is worth keeping it,
but at least for Apollo it seems to be clear that noone ever used
kernel 2.4 or 2.6 on this platform.
