That's complete gobdlygook to a non-technical user.  They won't know what 32 or 64 bits are (and it makes it sound like Kubuntu requires far more technical understanding than they have).  Boot may also be an unfamiliar term.

It hasn't been that long since Atom 32 was in large scale production. 

I'd prefer to give Ubuntu a year to go first and work out both technical issues and appropriate messaging.  We've had good success with this kind of approach in the past.
