Let's step back a bit

While I mostly agree, there are still a number of new mainstream CPUs which don't support hardware virtualisation, mostly aimed at the budget or mobile market. I know if I could use KVM on this laptop it would make my life a little easier. I've never used Xen so I don't know if it would be worth the effort for my purposes, but I'd be a lot more likely to try if it were in the kernel already.
