So is this the legacy PS/2 keyboard connector? If so, I think I may be able to test this really soon

Historically speaking yes, but on at least some laptops the built-in keyboard uses PS/2 and looks like an i8042 to software. The BIOS can use SMIs to emulate a PS/2 keyboard when a USB keyboard is used and the system hasn't yet indicated that it understands USB. That could be the case if U-Boot was being used more as a bootloader and there was a traditional BIOS underneath that did fancy things like that.

Applied to u-boot-x86/master
Thanks,
