Usage: $0 <s4|s4k|s3|s4hy|s3k|s4simdev|s4simcore|s3simdev|s3simplatform|s3simcore|s4simcpu> [watchdog port [maxnum]]

Possible deductions:
simdev fails                 -> no BIOS issue
simcore passes AND s4k fails -> BIOS issue
s4simcpu fails		     -> no BIOS issue + CPU hotplug bug

Only use coresim on machines that switch off power to busses in ACPI.
