Remember something here. IBM tuned the hardware to this, and to an extent they tuned the software on top of VM. They have a lot of cards to play that Motorola m68K chips did but x86 does not.
Im hoping transmeta can manage to add a virtualised 386 mode to their chip. Here's hoping they are listening ;)
In the Linux case we have another weapon (other than fear suprise and the cuddly penguin) which is that we don't give two hoots[1] if the kernel running on the hypervisor is not a normal x86 kernel. If it provides the APIs and it runs x86 user space its fine.
Consider the user mode kernel as a more interesting starting point.
Alan [1] Arguably we don't give one hoot or even a ho[2] either [2] half a hoot
