W Window system supports 1, 2, and 4 bit-plane planar (and 8-bit chunky)
modes and can works on top of a Linux framebuffer:

It's a long time since I've tried it on Atari (MiNT), but few years ago
I updated it to work x86 Debian Stable and added Debian packaging for it.

The package might build and work as-is on also on m68k Debian (it's
fast to build; small, uses plain makefiles and C), but probably one
needs to tweak it a bit.

If somebody tries it, I would be interested.  And if you think it's
still useful, I can fix problems in it.

(I wouldn't configure it so that it opens port to network though,
it's very naive and doesn't provide any of the X security features,
even session cookie.)

That would be monochrome...  For that you need (e.g. emulated)
monochrome monitor.
