That would require a lot of changes to save/restore the segmentation
register at kernel entry/exit since there is no swapgs on i386. 
And will be likely slower there too and also even slow down the 
VMI-kernel-no-hypervisor.

Still might be the best option.

How did that rumoured Xenolinux-over-VMI implementation solve that problem?
