Kernel is insanely vulnerable anyway.
Care to quantify and prove this?

Virtualisation does not seem a solution to me. Any systematic solution to security of hypervisors seems like it'd apply equally well to traditional kernels, surely?

Linux may be somewhat secure if one limits it to simple routing and firewall-related tasks. It's certainly not secure if one decides to use it, for example, to host world-accessible NFS shares or try to contain malicious local users.
And by this point in time, it can't really be fixed short of rewriting it in a safe language.

A way to get a more secure Linux kernel is to use the large PaX/grsecurity patch, which prevents a number of classes of vulnerabilities from successful exploitation.
