[openfirmware] OpenFirmware - PS/2 keyboard

[Samuel Hodgkins]

So, I've been experimenting with booting OpenFirmware on some random x86 
hardware. Chainloading it from GRUB works and is simple and loads to the 
grey/white 'Open Firmware' screem with an 'ok' prompt near the top and 
the cursor blinking in the absolute top-right of the screen. However, I 
can't seem to type anything into the 'ok' prompt. As the tested machine 
does not have a USB keyboard but a PS/2 one, do I need to alter the 
configuration to build a PS/2 driver into ofwgrub.elf?
