    mainboard/asus/kgpe-d16: Limit HT speed to 2.6GHz
    
    The CPU <--> CPU HT wiring on this board has only been validated
    to 2.6GHz.  While higher frequencies appear to function initially,
    and in fact function when only one CPU package is installed, dual
    CPU package systems will lock up after around 6 - 12 hours of uptime
    due to presumed HT link errors at the higher (>= 2.8GHz) HT clocks.
    
    If applications are not being used that stress the coherent fabric,
    then the uptime before hang may be much longer.  Users attempting
    to overclock the HT links are advised to "burn in test" the HT links
    by running memtester locked to a node with no local memory installed.
