I talked to some amd guys about this. We think it is doable. You need an
SMI handler that does nothing more than fix up the stack with a pointer
to a kernel assembly thing that does a soft interrupt. Then you do a ret
from SMI mode and you end up back in the kernel where you want.
If you study SMI mode a bit, we can do this.
