Strangely, the solution to this problem is to tell coreboot to *not*
handle the PS2 init and leave it to the payload.
using value
CONFIG_DRVIER_PS2_KEYBOARD is not set
results in the ps2 keyboard working fine when the payload init's it.
I checked devicetree and the mappings look correct from the ioport dump
and superio dump, so unsure of why the coreboot init would cause this
problem, but the solution seems to be "let the payload handle it"

Santity check;
PS2 keyboard, connected directly to PS2 port, works fine with stock
ASUS firmware.

Been playing with this board and have ran into a weird problem. I
cant get a PS2 keyboard to work with this motherboard under
coreboot. Ive used direct PS2 keyboard connections, Ive used PS2
splitters and PS2 KVMs and none work. PS2 init as an option is
present and selected in the coreboot config
(CONFIG_DRIVERS_PS2_KEYBOARD=y)
Im using current master of coreboot, and have tried the keyboard via
the PS2 port in multiple permutations of direct connect, with
splitter and also via KVM. None of which work. Ive tried with
different payloads including coreinfo and seabios, none of which work.
This is proving to be a challenge as im trying to make this board
the first port of a desktop board to heads firmware. Its worked well
so far, the only sticking point is the PS2 keyboard functionality.
USB keyboard is not really an option when using heads+qubes.
I cant find any refernece to ps2 or 8042 in the serial console,
until the SeaBIOS payload takes over. That displays the following;
Found 1 ltp ports
Found 1 serial ports
Got ps2 nak (status=51)
Does anyone have any thoughts or pointers?
Cheers
