This is very interesting!
But, I am not yet very convinced that the data sequence 53 02 14 is
the indication of GlidePoint.
Are you very sure that the pad on Z505DX is a GlidePoint? Is there
any VAIO's manual or doc identifying this pad as GlidePoint?
Does it behave like GlidePoint? You can verify this by doing the
following:
1. Boot the kernel with our patch.
2. Become root and kill `moused' if it is running.
3. Run `moused' in the debug mode as follows:
moused -d -f -p /dev/psm0 -l 2
4. `Tap' the surface of the pad. If this action is reported as
the button 4, the device is acting like GlidePoint.
5. Hit ^C to stop moused.
ALPS has produced various models of GlidePoint and there are some
GlidePoint models which do NOT report `tap' action as the button 4.
These models are not recognized as GlidePoint by the psm driver,
because they behave like ordinary two or three button mice and require
no special handling.
(The models which report `tap' as the button 4 DO require special
treatment to detect the button 4.)
BTW, I am very positive that VAIO 505GX, 505RX (and possibly other
models) come with VersaPad.
