Just as another datapoint.  I had been using SCHED_4BSD and saw those high
load averages.  I then switched to SCHED_ULE and see the same thing.  With
next to no user applications running I sit just above 1 and with my normaly
X environment running (where I normally sit well below 0.5) I'm seeing
between 4 and 5.  Like others I don't think the load is representatively
true.  And while this may be more aesthetics than anything (not really
effecting me in any other way right now although it makes xload look
pretty), some applications do track load avg during operations... such as
say sendmail.
