When I load the module with the option debug=1, it turns on and off my backligth and my wireless card, so I think it is working fine. Here what dmesg says:
samsung_laptop: module is from the staging directory, the quality is unknown, you have been warned. samsung_laptop: found laptop model 'X520' This computer supports SABI==f48b4 SABI header: SMI Port Number = 0x00b2 SMI Interface Function = 0xc0 SMI enable memory buffer = 0xc1 SMI restore memory buffer = 0xc2 SABI data offset = 0x0f00 SABI data segment = 0xdf01 ifaceP = 0x000dff10 sabi_iface = ffff8800000dff10 backlight = 0x01 backlight should be off backlight = 0x00 backlight should be on backlight = 0x01 wireless led = 0x01 wireless led should be off wireless led = 0x00 wireless led should be on wireless led = 0x01 brightness = 0x08 atkbd serio0: Unknown key pressed (translated set 2, code 0x89 on isa0060/serio0). atkbd serio0: Use 'setkeycodes e009 <keycode>' to make it known. Now I think I need only to use the setkeycodes command to have these new commands under my fingers :)
Thanks for that!!
