I think that's usually a BIOS issue, but not always.  There are also
some early P4s that set the HTT flag but only have one core.  That's
valid since all the flag means is that you have the extra instruction
which says how many cores you have.  I'm pretty sure that doens't apply
to 2.8GHz CPUs though.
