I'm not sure what my default clock source is (where does one look to determine this?), however I just booted with clock=hpet and things don't seem to be particularly better (50% IO wait time while evolution is starting, a process which takes over 5 minutes; this is with Jens' patch). These numbers are common with Jens' patch (which is a bit of an improvement, without the patch evolution pegs IO wait times at 70%+ and is very sluggish even after starting).
