I've added COM and LPT ports and set them up to loopback properly (COM->COM, LPT->KBD, KBD->LPT). It's not working yet, so I'm diving into the ROM code to try and figure out what's actually going on.

The disassemblies unfortunately almost completely miss most of the failing diagnostic code (e.g. the interrupts test at ~F4C30) so I'm having to disassemble manually.
