Run Ubuntu from SD Card on Android Tablet I'll be acquiring my first tablet in a few weeks, and haven't tinkered with Android much besides my 1st gen Motorola Droid (I had an HTC Sense, but a power surge fried it and turned it into a brick, same with my old laptop)

I feel like such a noob asking this but first I want to clarify that.... I DON'T wanna install Ubuntu on the tablet! I still want Android, I just wanna be able to run Ubuntu directly off of a SD Card or Flash Drive. Now I have Ubuntu 11.04 on my old flash drive, and was wondering if I can boot directly to Ubuntu from my flash drive on the tablet. I figure it's possible, just don't know if it's a simple plug in and go type concept, not sure if I'll have to install any additional applications in order to get it functioning properly. I figure it's more then possible. I just want to know what I'm doing prior before I do anything. So if anyone has any tips it'd be greatly appreciated.
There's a FAQ from when Ubuntu announced it was working on Ubuntu based tablets. There, they state:


  The only way to get an Ubuntu tablet is to buy a tablet built and supplied with Ubuntu by an OEM partner of Canonical


So I would say that Ubuntu is not, and will not, be capable of running on any existing Android tablet. Full FAQ can be found at Media FAQ For Press Pack: Tablet.
