As a person who works on the user-space interaction of those with 
desktops [1]: Urgh.

I already have 3 (probably 4) types of accelerometers to contend with, 
I'm not fond of adding yet another type.

Is there any way to get this hardware working outside the SoCs it's 
designed for (say, a device with I2C like a Raspberry Pi), so that a 
kind soul could handle getting this using the right interfaces?

Cheers
