Четыре процессора вместо двух

Приветствую ALL!
Вот такая проблема - есть двух процессорный сервер аквариус (вообще-то он Gigabyte GS-SR125), но не в этом дело... Дистрибутив Slackware 9.0 ядро 2.4.20, два процессора. В ядре тип процессора P4, включена многопроцессорность. Так вот определяются почему-то 4 процессора вместо двух, причем у последних трех богомипсы одинаковые. Может кто-то знает что с этим делать, и чем это может грозить?
