I know you haven't been just tweaking numbers ;) But in the case of the patch that provides different behaviour depending on whether a sleep is interruptible or not really smelt of papering over symptoms. Now it might be that nothing better can be done without move invasive changes, but I just thought I'd voice my concerns.
Oh, and remember that your desktop load is devoid of make -j big compiles, so that is not a requisite for good interactivity.
