So, I'm ready to wipe my XOOM!
I'll be doing this with a US XOOM, however to do this you won't need a US XOOM.
download the files relative to your xoom region at motodev (I recommend US)
I'm downloading them now...I will add another reply when that's done downloading!
The files have downloaded. Rename the existing recovery.img to recovery.bak.img, because that's CWM. Now extract GED files into the XOOT directory.
Start the GED flasher. Ignore the warning that says "MAKE SURE THAT IT IS NOT A US XOOM". Now begin the flash!
As soon as that's done, do the OTA update.
Now that the flash is done, reboot your XOOM. Fill in the setup wizard when it appears.
Keep updating until you're at OTA 3.2.1
Now rename recovery.img to recovery.img2 and rename recovery.bak.img with recovery.img
First choose to root your device (I KNOW YOU HAVEN'T FLASH RECOVERY, JUST LISTEN).
When that's done, reboot normally and flash Recovery. As soon as that's done, restart into recovery. This will give the XOOM no chance to run the deflashing things.

Reboot system now
Rooted!
