Try making the guest CPU a 486 -- we've found in the past that
something in early boot divides by zero based on RDTSC values
ending up too close together [cf some comments by David Gilbert
in https://bugs.launchpad.net/qemu-linaro/+bug/893208]
I don't know if this is the result of the host CPU just being
too slow or of our RDTSC emulation not being very good...
