I have to believe that you have heard of Wikipedia:
I just did not know what to use for my googling to get to this. Thanks.
This wiki page even lists the OQOs as examples of crusoe processors.
Now in terms of actually running Centos on this device, how do I enable crusoe processing?
At the bottom of that page you were directed to is a link, Linux on laptops and notebooks with Transmeta CPUs: http://tuxmobil.org/cpu_transmeta.html
Which leads to a page which shows you in detail how to do it with SUSE.
Maybe that might get you going?
