I received one of Eivind's kits last week and built it on Sunday.
The build went pretty smooth and with the great instructions on github I had Indiana Jones and the Fate of Atlantis running within a couple hours.
Good to hear! 😀
I'll try to address some of your questions:

I did install MS-DOS 6.22 and I'm now struggling to get any USB mouse working (I don't have any PS/2 or serial mouse). Tried five different mice, different USB ports, different drivers, in combination with different keyboards and so far no luck. Any help is appreciated. I also couldn't get the mouse to work in Freedos but I spent less time trying there.
Make sure to use CuteMouse (CTMOUSE.EXE) either version 1.9 or 2.1, as those talk to the BIOS (which has a PS/2<->USB mouse emulator), instead of PS/2 directly.
I've tried a couple of modern optical mice with no issues.

- Thinking about trying to connect the gameport pins of the sound chip to the Pi (probably via some digital potentiometer ICs over I2C) and run a modified MT32-PI to support a USB joystick
Not sure how you'd go about modifying mt32-pi to achieve this, it's bare-metal software after all. I'm thinking I'll add a standard gameport connector (MIDI+joystick) in a subsequent board revision, but USB joystick/gamepad might be hard...

- Would be nice if the holes on the board would line up with the holes on the Pi Zero to mount a cover plate on standoffs
Yeah I suppose that makes sense. Noted!

- I would like to mount the VGA port somewhere and maybe also add 5V on pin 9 to power a VGA to HDMI adapter
When designing the board, I did contemplate adding a pin header to connect a short cable from the VGA card module to, and routing the signals on the board to a VGA connector. It seemed a bit over-engineered and space consuming, though - and I didn't quite see what value it would add. I guess adding 5V on pin 9 would be something, but I'm still a bit skeptical of the whole concept. 😀

- I need to do something about the display sticking out on the side
Did you solder the display onto the board directly? I would suggest using 4 Dupont wires instead, and mounting the display in a case of some sort (btw, take a look at my example case on Github.
