Secondly, I'd like to add support for reading the accelerometer values,

I know that no one is happy of directly accessing the raw I/O ports, but
all my attempts of reading these values through the ACPI interfaces or
the EC fields have failed: the fields are always set to 0.
So, what I plan to do is to check the DMI information, and if the
machine is a S10-3t I would you the code linked above to read and report
the accelerometer values. Would that be acceptable?
I'm wondering if the accelerometer driver is also compatible with the ThinkPad SL laptops. It is said that their firmwares are quite similar to the IdeaPad ones. As they have quasi nothing in common with the normal ThinkPad series there's no support for them in thinkpad-acpi/hdaps/tp_smapi.
So far what I know is SL400 has similar firmware with asus-laptops, and other SL are using thinkpad-acpi.
The EC of the ThinkPad SL laptops is from ASUSTeK as far as I know. At
least it looks like that in the DSDT. So asus-laptop handles some
hotkeys. No ThinkPad SL can be handled by thinkpad-acpi, because they
are totally different.
Features like bluetooth rfkill and accessing the blue LED in the Lenovo
Care button are still not supported ([1] can do that, but never was
accepted for the kernel).
I have a SL400 and tried to examine the DSDT but found nothing about accelerometer sensor.
There should be an accelerometer in your SL400. Try the driver mentioned
in this thread.
I compiled the iaps module and loaded it successfully on my ThinkPad SL. There is also data passed by the driver to the input subsystem, when I move the laptop. Is there a way to validate this data?
Which SL you have? If we can find out a standard interface, that will be good.
I have a SL500. It looks like the mailing list disliked my attached
DSDT. What are the limitations on this? It is available under [2] now.
