Well, that was certainly fast. Although, having an unlocked bootloader I'm sure helped this process just a tad bit. With the news coming to use courtesy of Koush, the Motorola XOOM now has a root method available for it. Although ROM Manager updates will come at a later time, you can use the guide listed below to get a head start on things:

Download the XOOM root zip.

Unzip the package.

Copy the files into your sdk folder.

adb reboot bootloader (skip the next 3 steps if you have already unlocked via fastboot)

fastboot oem unlock

wait for reboot

adb reboot bootloader

fastboot flash boot rootboot.img

fastboot reboot

wait for reboot

adb remount

adb shell push su /system/bin

adb shell ln –s /system/bin/su /system/xbin/su

adb shell chmod 4755 /system/bin/su

adb push Superuser.apk /system/app

Due to the SD Card slot being locked out at this time, a custom recovery cannot be used but one does exist for whenever it gets enabled for use. Be it by Google, Motorola or the developer community. Until then, just enjoy your freshly rooted Motorola XOOM and if you should so need some help; hit us up in the Android Central forums. [Koush] Thanks, to everyone who sent this in!
