well, I was thinking of a two layer lookup keyed on the event code
(0x9[02ce]).

the problem is that the decoded keypress (after the SN07 call) generates
duplicates, i.e.: 0x81 is fn+f1 for the 0x92 case and some "Mode" key
for 0x9c the an SR model.
I guess sending the whole combination as the scancode would do the trick
(0x9c81).
But as long as we can make it consistent with what sony-laptop currently
sends to userspace then we should try to have a map.
