I noticed something on one system on which I was trying this.  If the
BIOS has "logical cpu" disabled, then there is no HTT available, and
subsequently the machdep.hlt_logical_cpus is non-existent.  When I
went into the BIOS and enabled the logical cpus, the MIB showed up on
the next boot, and the system thinks it has 4 CPUs now :-)
