PBButtonsd

This release has an additional input handler that works around the synaptics trackpad driver that blocks certain event devices for exclusive use. Problems with an unstable autoconf package have been solved so that pbbuttonsd will compile and install as usual again.

This release now uses sysfs and open firmware to
detect the machine type and the I2C device to
which the LMU is connected. This leads to a more
detailed machine identification and a more
reliable detection of ambient light sensor and
keyboard illumination. A possible division by zero
error in the ALSA module was fixed.

This release now supports 255 brightness steps for
the keyboard illumination. Fading is now really
smooth. Some problems with machine identification
were fixed, especially with old G3 PowerBooks.
Code optimization was done to decrease CPU load
and a segmentation fault in the ALSA module was
fixed.

This release fixes a couple of small problems.
Disks are synchronized before calling a suspend
mode. The user is allowed to dim the display to
complete darkness even if the automatic brightness
controller is running. Furthermore, this release
won't use the vendor and product ID of USB devices
any longer because they were found not to be
unique. pbbuttonsd missed some input devices
because of this in the past.

This release has support for the ambient light sensor and the keyboard illumination of the latest 15" and 17" Powerbooks. The keyboard mode of USB keyboards can be set the same way as for ADB keyboards, as long as you use kernel 2.6.16 or later. As the first big step towards major future enhancements, the main loop and the input device management of pbbuttonsd was moved to glib. This change is the basis for moving pbbuttonsd's IPC system towards dbus-1, and to implement a dynamically loadable module system for user space device drivers (USDD).
