yeah, this laptop also has an "AT translated set 2 keyboard" that appears to 
be the real keyboard of the laptop on /dev/input/event0 and then a bunch of 
other stuff that is not really relevant

i wonder if there is any way to discover how many buttons a keyboard has? (if 
this is advertised by the device at all)
