Even with a single vcpu it's easy to cause an Oops with scrashme.
However, an fptest running in another process at the same time doesn't
seem to experience register coruption or anything else nasty. 

(http://www.codemonkey.org.uk/projects/scrashme/scrashme-1.0.tar.gz)

./scrashme -r -c113 >/dev/null  (vm86old)
./scrashme -r -c166 >/dev/null  (vm86)

It shouldn't be too hard to fix the Oops, but I'm not seeing anything
that would explain Robin's problem.
