It shouldn't matter. The virtual processor (just like a real one) starts up in 16 bit mode and is then set to 32 and then 64 bit mode by software. > Also, I haven't played with Linodes 'System Profiles' at all - I was > thinking I'd just create a new profile, add my Gentoo System Image and a > swap image to it, but assign the 64 bit kernel, then if it doesn't work, > switch back.
