I don't have that much =20 low-level knowledge of current CPUs). They made this so that Windows =20 XP is able to run with the dual-core CPU instead of requiring the =20 Professional version to use both CPU cores. So maybe we need to change the part in FreeBSD which handles the HT =20 part of the CPU...
