I beg to differ. Since at least kernel 2.4.26 (probably earlier)
the standard Linux kernel does support HT and turns it on by default,
as long as it's compiled with CONFIG_MPENTIUM4=y; I am sure because I
have a machine running this way right now.

It's OK to check for HT this way: /proc/cpuinfo will report two cpu's
for every ht-enabled processor you have on board.

If it's indeed running with HT and you need to disable it, try "noht" on
the kernel boot line; if your kernel doesn't support it, you will need
to recompile it with CONFIG_M686 instead of CONFIG_MPENTIUM4.

As this is way off-topic, if you have further questions please fell free
to email me directly, it will be a pleasure to help.
