+While examining the firmware from other thinkpad models, the keyboard matrix
+table has often been located.  To avoid needing to locate these tables
+multiple times, they are recorded here.

+One think noted from this examination was that all the xx70 and xx80 matrix
+tables checked were identical (thus the keyboards in those models are
+interchangable with no firmware changes)
