No, there isn't any PS2 keyboard support on the Iyonix.

aA previously mentioned the kernel contains very simple USB drivers designed
to only detect a keyboard on startup. However having certain USB devices
present can slow the enumeration, so the kernel gives up looking in order not
to slow the boot sequence.

It may be possible to avoid this problem by swapping which USB sockets the
keyboard and parallel converter are plugged in to. Particually ensure that
they keyboard is directly connected and the converter is hung off any hub.
