[Bug 631305] [NEW] Fn-F5 / Fn-F6 don't produce scancodes on Sony VGN-CR120E

[Walter_Wittel]

Public bug reported:

On 9.10 Fn-F5 and Fn-F6 lower and raise the display brightness on my
Sony Vaio VGN-CR120E, but this no longer works in 10.10 Beta (booted
LiveCD). Not sure if it worked in previous Maverick kernels or in Lucid
(too many things broken so I never upgraded from 9.10).

'sudo showkey -k' outputs keycode 470 for Fn-F5 and 471 for Fn-F6, but
'sudo showkey -s' doesn't output anything when the keys are pressed and
the display brightness is not changed. I can change the display
brightness from the slider on the 'Power Manager Preferences'
application.
