Those events (see linux/sonypi.h) can be polled using the character device node
/dev/sonypi (major 10, minor auto allocated or specified as a option).

A simple daemon which translates the jogdial movements into mouse wheel events
can be downloaded at: <http://popies.net/sonypi/>
+Another option to intercept the events is to get them directly through the
+input layer.

This driver supports also some ioctl commands for setting the LCD screen
-brightness and querying the batteries charge information (some more

commands may be added in the future).
This driver can also be used to set the camera controls on Picturebook series

Motion Eye camera.
Please note that this driver was created by reverse engineering the Windows
Driver options:
---------------
-Several options can be passed to the sonypi driver, either by adding them
-to /etc/modprobe.conf file, when the driver is compiled as a module or by
-adding the following to the kernel command line (in your bootloader):
-
- sonypi=minor[,verbose[,fnkeyinit[,camera[,compat[,mask[,useinput]]]]]]
+Several options can be passed to the sonypi driver using the standard
+module argument syntax (<param>=<value> when passing the option to the
+module or sonypi.<param>=<value> on the kernel boot line when sonypi is
+statically linked into the kernel). Those options are:
-where:

some Vaio models don't deal well with this option.

driver disables all APM management for those keys, by enabling the
ACPI management (and the ACPI core stuff is not complete yet). If

- since all development was done by reverse engineering, there is
_absolutely no guarantee_ that this driver will not crash your
laptop. Permanently.
