Arnout Boelens sent (a year ago, to the Debian BTS) the keyboard layout of his laptop (Asus 6000) which is currently not supported.

// Asus A6000 series Keyboard
partial alphanumeric_keys
xkb_symbols "asus_6000" {
  key <I20>   {       [ XF86AudioMute         ]       };
  key <I2E>   {       [ XF86AudioLowerVolume  ]       };
  key <I30>   {       [ XF86AudioRaiseVolume  ]       };
  key <I6C>   {       [ XF86Mail              ]       };
  key <I32>   {       [ XF86WWW               ]       };
  key <I10>   {       [ XF86AudioPrev         ]       };
  key <I19>   {       [ XF86AudioNext         ]       };

  key <I22>   {       [ XF86AudioPlay         ]       };
