Lenovo Idepad U330 DSDT
Hi,
I've noticed that in kernel 2.6.33-rc5, acer_wmi started getting loaded for my
Lenovo Ideapad U330 laptop. Somehow, out of the blue, it started loading and
doing weird stuff to me wifi rfkill (bug 15164), which... is a good thing :)
First of all, the wifi rfkill works using acer_wmi, which gives some hope :)
Second, it seems that my Ideapad shares quite a lot of code with other Acers,
namely 4810TG. I was able to turn off my Ati card and use only the Intel one in
switchable graphics mode, thanks to this code made for Acer laptops:
http://ubuntuforums.org/showpost.php?p=7933876&postcount=11.
I've poked around my DSDT and it seems that the AMW0 and WMI0 things are there.
Under Windows, there is a separate software rfkill for WiFi and Bluetooth, but
both of these are controlled by the hardware switch. It would be fantastic to
be able to use the bluetooth rfkill under Linux.
Could someone, who is more familiar with all this low-level stuff, please take
a look into the DSDT of my laptop and tell me if there is any faint possiblity
of it being compatible with acer_wmi?
Also, the dmi stuff on my laptop is a little borked, as dmidecode reports:
Handle 0x0001, DMI type 1, 27 bytes
