huh. it is possible the 64 bit version was overwitten when i formatted last week, as I didn't check the image to see which one I installed......suck. ok, i'm gong to reinstall, with the 64 image, and then get back to you.. (luckily, installs of ubuntu take about, a second)

i686 means clearly does pertain to x86......damn. my bad. will write back once i reload.
