NeXTStep and OpenStep are the precursors of Mac OS X and are retail (abandoned but).
The source code of the bootloader evolved in the currently available at http://opensource.apple.com but who knows how much it changed.
However I can test it with any you want, and if you want to add me to instant messaging you could guide me in the debugging.

Ok, QEMU is absolutely unable to boot nextstep/openstep, while using SeaBIOS.
Changing to old Bochs BIOS, makes it work, however no video is output (until NeXT starts using VESA).
Is nextstep/openstep something that can be freely downloaded?
It would help if you can extract some SeaBIOS debugging info. I've uploaded a SeaBIOS image with the debug level set to 8 and serial debugging enabled. It is at:
Can you use this image with qemu, add "-serial file:mylog" to qemu's command line, and forward the resulting "mylog" file back?
Also, please include the full qemu command line that you used.
