Device drivers are going to be different in Boot Camp and Parallels because the devices themselves are accessed differently in a virtual machine/shared OS environment vs. exclusively in Windows. That is why there is a custom boot into Windows for Safari and a different custom boot for Boot Camp. Installing the latest version of Boot Camp must be done by burning a CD from the Boot Camp Assistant program in your Utilities folder (after you download and install the latest 1.3 beta from Apple). You then boot into Boot Camp directly (by restarting your Mac and holding down the option key) and install the new drivers from the CD after you get to the Windows desktop. But remember, those drivers only get accessed while you are booting directly into Boot Camp. Parallels uses its own drivers for your hardware to interact with Windows as a virtual machine.
