Keyboards in laptops don't use round cables like that, it's flex cable. The keyboard controller reads the laptop kbd as a matrix, you've got row
and column contacts that it scans. So it's not like a keyboard for a desktop.
Next, for a EE he's pretty lame, because it's not a "programmable interrupt controller", a mistake a designer would never make.
Next, that particular part doesn't have a mac or phy for an ethernet connection, so there's no way you could "hook it to your ethernet board" and
interrogate it. The ethernet board used is "dumb" and couldn't build the frames itself, either. So that can't work that way.
Finally, there's no need for it. If you were shipping them "pre-loggered" you would just rewrite the keyboard controller code a bit and/or add a
driver or rootkit to the system software and send it that way. You don't need extraneous hardware.
