Thanks. Your attached udev.txt confirms that the keymap matching worked:
P: /devices/platform/i8042/serio0/input/input4/event4
[...]
E: KEYBOARD_KEY_85=brightnessdown
E: KEYBOARD_KEY_86=brightnessup
[...]
and your evdev output on event10 confirms that the device *claims* to
support KEY_BRIGHTNESS{UP,DOWN}.
If you don't get any events on either device, this must be fixed in the
kernel keyboard driver, reassigning to linux. Any chance you could try
to install/boot the raring kernel on current saucy, to check if that
brings back the keys?
** Package changed: systemd (Ubuntu) => linux (Ubuntu)
** Changed in: linux (Ubuntu)
Status: Incomplete => New
** Summary changed:
- [keymap] display brightness keys stop working after saucy upgrade
+ display brightness keys don't generate evdev events after saucy upgrade
