Sorry for the long delay. Eventually I've found time to test the patch
and fix a bug: the axis conversion was set too late, preventing the
calibration to work.

The attached patch should make your modifications fully working with the
hp laptops :-)
I guess the best is to fold it into your patch and I'll ack the new

Must put the axis info before using it.
