This is not relevant to PS/2 keyboard but the "cannot manage" messages 
about USB devices reminded me that I've only ported the OHCI driver from 
coreboot so it likely won't work on a PC where UHCI (or EHCI) is more 
common. If you want to use USB peripherals then you may need to port at 
least one of those too. If you also want to boot from USB then maybe the 
usbmsc driver will also be needed which I've also skipped (I've only added 
a HID driver in OpenBIOS sufficient for a keyboard so that's the only 
thing expected to work currently).

In case you've tried booting from an HDD not from a USB drive then I'd 
check if that has a driver (if the ATA/SATA controller is mentioned in one 
of the cannot manage lines then it's likely missing a driver). Looking at 
drivers/pci_database.c I think we only have driver for virtio and CMD646 
based IDE controllers although the IDE one may work for similar 
controllers, but I'm not sure about that.
