This update contains, according to the technical note:
“This update resolves issues with the trackpad and turns off the red LED on the digital audio port on notebooks when it is not in use. It also adds support for the Magic mouse and wireless keyboard. It is intended only for use with Microsoft Windows XP and Microsoft Windows Vista on one more computer already using Boot Camp. "
