I'm simply using "top" on both systems, one is a MacBook Pro C2D,

No.... it doesn't lie, it is telling you exactly what it was written
to tell you. The issue is are you interpreting what it is telling you
correctly and/or are you really comparing equivalent things... or is
some other unconsidered factor throwing off the comparison.
For example exactly how long is each really sleeping? Is the Linux
build really sleeping about 1us? Is the Mac OS X build? If not then
the comparison is broken since you are comparing CPU load assuming
that each is sleeping for the same amount of time. etc.
