Trying to use disklabel from sysinstall with those geom flags resulted
in a panic, I got the following trace from the debugger:
panic: spoiling cp->ace = 1
cpuid = 1;

I don't know anything more useful I can do than that, so if there is
something tell me. However, I have managed to somehow lockup the serial
console so I can't do anymore until tomorrow.
