Bug: changing keycodes generated by sony-laptop doesn't work

[John Hughes]

Something about the way sony-laptop sends scancodes and keycodes to the 
input subsystem doesn't work.

1. using the /lib/udev/keymap utility to show the scancodes and keycodes 
generated by the Sony Vaio keys device shows them  out-of sync:

start keymap, press EJECT (mapped by sony-laptop to FN_E) twice, then AV 
MODE (mapped to PROG1) twice:

#   /lib/udev/keymap -i input/event5
Press ESC to finish
scan code: 0x00   key code: fn_e
scan code: 0x1B   key code: fn_e
scan code: 0x1B   key code: prog1
scan code: 0x20   key code: prog1
^C

Notice that each time a key is pressed the scancode shown is the 
scancode of the previous key.

2. Changing the keycode for a given scancode has no effect:

#   /lib/udev/keymap  input/event5 0x1B ejectcd
setting scancode 0x1B to key code 161
#   /lib/udev/keymap -i input/event5
Press ESC to finish
scan code: 0x00   key code: fn_e
scan code: 0x1B   key code: fn_e
^C
