OMV on Pentium 4 HT

Hello,
i cant find any info about this config in web... If anyone can tell me am i wrong...
I have OMV installation on Intel Pentium 4 [3Ghz] procesor, which supports Hyper threading technology, but i cant manage to activate it. while i search for some info, i found that, the i386 architecture isnt compatible with intel HT. as far as i686 debian kernel have intel HTT support.
howewer, i cant find any OMV iso with 686 arch.
Is this safe to manually change kernel under OMV without any further complications? or there is another way to make system recognizing two threads in Pentium 4?

Thanks for any help - Ivox.

I have pentium 4 HT 3.0 (or 3.2ghz) socket mpga478 (im not sure, but i think its prescott) on this machine.
if changing kernel to i686 under working OMV installation do not affect on system, or provide any incompatibilites after changing, i'll try to follow this topic on forum.
Thank you
Ivox.

Thank you, i have updated kernel to 3.2.0 i686, and it can start.
but system works unstable, need package updates. Are this packages for i384 compatible with i686?
i cannot find any debian i686 package sources, and still updating to i386 arch packages.
does this need any more solution?
Thank you

i want to enable second thread, because im running on it OMV, and some other things like TS3 or Transmission. When all are used in same time at peak sometimes system is heavily overloaded. I think its the best way to increase stability and overall performance of this machine. for now CPU is recognized as 1 core, while 686 kernel recognizes 2 cores well, but throwing many errors including apache2 and OMV couldnt start properly
