Unless someone here just happens to work for BA and has the schematic we won't be able to help with that. Fixya is a volenteer thing so there is a fairly varied tech base represented here so you never know.
I've looked at that board (I think) and the ic you are looking at is a 16QFP?
I'm not 100% sure but I think it was a atmel part.
You may end up having to pull it to actually id it. The schematics are going to be rather unlikly to get too far out of the factory.

Well I searched high and low, but couldn't find anything at all.... usually, though a KB controller, seldom fail? Usually, it is the Interface, that has been "Spiked" or a Power Supply problem. Use you 'scope and feed a signal in. and trace it to where it stops... You could also use a signal generator, say an old radio, and use a capacitor to feed in the signal, to a handy point, and use an old, earphone, with Probes attached to it.. Also check, you power supply, is that OK, 'cause if it's NOT nothing else can be..
