Sammy regularly (a few times per year) submits patches for Sun 3/3x, so
I assume it still works.

Apollo had probably less than a handful of users ever.

As already mentioned, Amiga, Atari (especially ARAnyM these days), and Mac
are the biggest m68k platforms in active use. Not all drivers receive the
same amount of regression testing, but especially the network and SCSI (the
ones we still have; people regularly complain about the removed NCR53C9x
drivers) drivers should be in good shape.

The VME boards have always been quite exotic, just like the HP9000/300 and /400
workstations.

Q40/Q60 probably lost their last few users, too.
