The problem is drivers - although Android runs a Linux kernel, it is heavily modified, and Google has slated Linus & co for refusing to accept their patches into the mainline Linux kernel (at one point, Google threatened to fork the entire kernel and run with it themselves).
If you've nothing to lose (ending up with a "dead" tablet), I'd do as MP suggested and give Ubuntu a try, following all their guides, as Canonical seem to be the ones pushing in that direction the strongest
