"top" consistently shows as 0.00% for me while running top. On a relatively idle machine, only X-related processes (xosview, kmail, XFree86, mozilla) ever show as anything other than 0.00%, so if you are running in console mode, 0.00% might quite possibly be right for everything. The CPU will show up as right busy, though, if, well, it's busy.
