Hi,

The sensors HAL is definitely where you should look to make these changes.

It should be a simple matter of swapping the values reported for x and y by
the driver.
(and/or reversing the signs) to get the 90degree offset in orientation
right.

The sensor-HAL for froyo being a single-file (Sensors.c) in either:
- hardware\sensors\ or
- device\<vendor>\<product>\sensors\

Just swap the vars accordingly for *ACCEL_X* & *ACCEL_Y* events in the
*data_poll* function implemented in *Sensors.c*

A little experimentation will give you the complete idea
of how acceleration values determine the orientation.
