To enable the ps/2 keyboard, you need to cap the four jumpers jp106,
jp107, jp108, and jp109. That's the group most closely located to the
keyboard connector.

Are you using the ramdisk supplied by Cirrus? That should have the
devices in /dev you need, if you're using your own that is what I can
think of.

Of course, it could be something entirely different, but 'do not work'
is not very descriptive.

The Cirrus ramdisk comes with nano-X, see the demos in /usr/nanox
