Hi,
I have exactly the same problem on my Linode. It's been that way ever since I changed to the 2.6.20-linode28 kernel.
Load average hovers around 0.4 all the time for me.
My vmstats show 100% idle times:
Code:
procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu----

I also set up a log to see if there was a trend, but the graph is pretty much flat, as you can see:
Code:

The load is wrecking havoc with my monitoring - I was actually considering opening a ticket, but then I saw your post.
