No. Quite the reverse. I just effectively wrote "you _cannot_ do that". And we won't even tell the details of _how_ you cannot do that. In fact, even inside transmeta you cannot do that, without having a specially blessed version of the flash that allows upgrades. If you ever see a machine with a prominent notice saying "CMS upgraded to development version", then that's a hint that it's a machine that TMTA developers could change. But even then you'd have to know how to change it. Think of it like the Intel microcode update, except on steroids. Big steroids.
