Oh goody..

Just had a look at the datasheet. 'Interesting'

I'm particularly looking forward to seeing use of the on gyro master
i2c bus for talking to an external accelerometer :)

There are quoted conversion parameters for going from the raw readings
to degree's per sec.  You 'could' apply them in kernel I guess, or maybe
provide details of what they are to userspace....
