IIRC, on a two CPU system the numbering is as follows:
0 : 1st hyperthread, 1st CPU
1 : 2nd hyperthread, 1st CPU
2 : 1st hyperthread, 2nd CPU
3 : 2nd hyperthread, 2nd CPU

If you don't want to use HT, just assign to 0 and 2 (for instance) and then 
you'll only have one domain running on a physical CPU at any time.

HTH,
Mark
