It's an Intel Atom D525 which 
according to the specs does support hyperthreading, I did think that 
may have been why.

Sadly that may be where my knowledge of building things under Ubuntu 
(or any Linux) falls somewhat flat.  I'll take a look on-line for how 
to do it but if you can quickly let me know that'll make the turn 
around faster.
