Comment 49 for bug 595896

Yeah, I think the situation should be clear now, given different results of
dmesg on 10.4 and 10.10. In 10.4 thinkpad_acpi doesn't work at all, which
leads to mute button behaving in its default way (works, but only affects
the speaker); in 10.10 thinkpad_acpi gets loaded and take over the mute
button but unfortunately makes it unusable.
