[PATCH 1/5] Fix mute key for T series Thinkpads

[Jerone Young]

    ACPI: Add Thinkpad T400 & Thinkpad T500 to OSI(Linux) white-list
    
    acpi_osi=Linux helps the mute button work properly by sending Linux
    a mute key press. This is the same behavior as seen with the Thinkpad
    T61 already on the white list.
