Is it possible to produce a large scale system-level program (esp. with 
smp) that is auditable?  I think not.

kqemu is particularly difficult because it interacts with the hardware 
in complex ways.

It's technically possible, but I don't think it's realistic.  No one 
wants to code for yesterday's hardware; every day there are fewer 
machines that need kqemu.

If you're interested in virtualization, but a cpu that supports 
virtualization.  If you want to keep your old cpu, keep your old 
software as well.
