Yes, I confirm this in X61.
*Without* "acpi_osi=Linux", the mute button toggles volume muting but is *not* seen by software.
*With* "acpi_osi=Linux", the mute button generate the key event but i have no software to handle it,
so this key events be omit and finally shows that the mute button not work.
My laptop: thinkpad X61 7675 ThinkPad BIOS 7NET30WW (1.11 ), EC
7MHT24WW-1.02
2.6.24-rc7 ThinkPad ACPI Extras v0.19-20080107
