The advantage the 68030 has is the PMMU. I don't think you can use virtual memory on a 68020. My first Linux machine was a IIsi, the little-brother to the IIci. But I had to put NetBSD on it because the Linux keyboard driver was broken.

You can use virtual memory on the 68020, but you need a 68851 between the 68020 and memory. The 68851 is an MMU coprocessor, like the 68881/68882 is a floating-point coprocessor.

  Or you could roll your own MMU for the 68020, like Sun and Apollo did.
