To add more .. did some experimenting. I found something interesting. So
if acpi_osi=Linux is passed on the kernel command line (this is done in
the kernel for T61 & T400 & T500) .. but when I do this. The proc
interface doesn't actually work anymore. It will light up the mute
button light though on my X301 & turn it off. But no effect to the
volume.
