@Jerone:
I beg to differ. We would like an *EVENT*, so that we can deliver it to the
audio subsystem to tell it "hey, the mixer state has changed, please check it",
instead of wasting CPU resources and power by doing *SLOW* IO to the CMOS NVRAM
chip at 10Hz to figure it out. If _OSI=Linux is required to get that event,
that's exactly what we need to do.
We DO NOT want it to send a keypress at *all*. We want it to mute, and we want
to know it was done. We also want to know when the laptop unmuted, for obvious
reasons.
KEY_MUTE coming from the keyboard is just utterly useless on a thinkpad. If
they had to rape Windows for it to work there, that explains a lot... the
older thinkpads didn't need any hotkey drivers to do the right thing, be it in
Linux, Windows, Novell, DOS, FreeBSD, or whatever other obscure OS you wanted
to run on them.
Jerone, I'd be thankful if you could send me a note after one or two months,
when I should be a lot less stressed, to get in touch with Lenovo about it. I
may be able to stop the "need for whitelist" madness for future models, but I
need to study the ACPI DSDTs in detail and without a box to test it on, it
won't be nearly as easy.
