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.

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?
