I build a snapshot of the acpi.git tree (2.6.23, 21. Okt 07) and had a working backlight control on my FSC Esprimo V5505. With a build from mainline (of today) and also from acpi (also of today) the key's don't work any more. The Volume-up/down/mute (Fn-F4/F5), the s2ram button (Fn-F12) work. Left are Brightness, Display-change, WLan/BT-Switch and Touchpad-switch. Brightness are Fn-F8/down and Fn-F9/up dmesg if "backlight down" is pressed: atkbd.c: Unknown key released (translated set 2, code 0xd9 on isa0060/serio0). atkbd.c: Use 'setkeycodes e059 <keycode>' to make it known. no output on "backlight up" Display is Fn-F10: Dec 28 22:53:51 legolas kernel: atkbd.c: Unknown key released (translated set 2, code 0xa9 on isa0060/serio0). Dec 28 22:53:51 legolas kernel: atkbd.c: Use 'setkeycodes e029 <keycode>' to make it known. Touchpad-Switch Fn-F6 (touchpad stops working atm, if used): First time pressed: Dec 28 22:55:22 legolas kernel: atkbd.c: Unknown key released (translated set 2, code 0xf1 on isa0060/serio0). Dec 28 22:55:22 legolas kernel: atkbd.c: Use 'setkeycodes e071 <keycode>' to make it known. 2nd time pressed: Dec 28 22:55:23 legolas kernel: atkbd.c: Unknown key pressed (translated set 2, code 0xf2 on isa0060/serio0). Dec 28 22:55:23 legolas kernel: atkbd.c: Use 'setkeycodes e072 <keycode>' to make it known. WLAN/Bluetooth-Switch Fn-F1: No effect, no dmesg (which is fine for me, imho). dmidecode: SMBIOS 2.4 present. 43 structures occupying 1553 bytes. Table at 0x7F6DF000.
