You're probably thinking of the 68LC040 that had no FPU. They did indeed have an MMU, though granted it was rarely used in the older MacOSes. The Virtual Memory required it, however, as do Linux and BSD OSes for 68k Macs (this is why VM and non-MacOSes don't work on Basilisk II and other 68k Mac emus - no MMU support).
Darn good chips for the era, it's an interesting What If if PCs had ended up with 68k procs.
Both the 89 and 92/92+ are running 10 mhz m68000 chips, just like the old Macs but 2 mhz faster. The latest ROM gives the 89 just over 600k mem total I believe. I could see Linux on it pretty easy, and since there's already a mk68k Linux port I bet it wouldn't take much at all to adapt to the screen and mem type.
