I'm about to submit a kernel patch for Karmic to fix this issue for many Thinkpads. For the T61 this is the case. But in the kernel it is listed to expose itself as Linux when the Bios queries it.

Lenovo has logic in the bios that will change the mute key from a just a controling the speakers at the hardware level. To sending the OS the mute key press instead.

This can be found in the kernel in
drivers/acpi/blacklist.c
