From http://www.linode.com/faq.cfm#how-do-i-get-my-fair-share-of-... , they state that you get access to the full CPU of the box (if idle/best case), or access to your fair share of the CPU (if fully loaded/worst case). For the smallest plans this could mean 1/40th the overall CPU if under load. They only put accounts of the same size on each machine.
