According to http://ark.intel.com/products/65470/Intel-Atom-Processor-D2550-(1M-Cache-1_86-GHz) it doesn't do speedstep as well. i386 fakes a table with high/low values for older processors that still have a fsb, which was mostly used before the code to fetch tables from acpi was added.
Thank you for your explanation. i386 it is then.
