There is usermod linux (a kernel patch) which provides a way to run a kernel in the user space. It's usefull for testing new kernels, but you can't switch to the new kernel and forget the other. I think something could be done if we had a real good bios (linux bios ?). Like this, the operating system could be a userspace linux. And we could have several...
