Guys, Thanks for the answers! In doing research on those options I too found that they were not need for Hyperthreading, but I needed something more to back up opinion.
Thanks Again.

I thikn none is needed for ht. Of course, mtrr raises performance. The other are not needed, afaik.

True for old kernels, not needed anymore.

No.
In summary, with 2.4.19 you do not have to do nothing to have hyperthreading. Other useful options are 'noht' to disable ht, and 'idle=poll', that I think improves latency.
