@Ben Gamari -- I cannot see that patch in v2.6.37? From the v2.6.37 source it seems unchanged, I also cannot see it in v2.6.38-rc1:

    int vm_swappiness = 60;

Also it is not at all clear that there is agreement on what is a good value for desktop, for example in comment #3 Robert says "swappiness=10 is a good setting for desktop" and in comment #33 Virgil states a contrary view "I actually prefer to use a value of 'vm.swappiness=100' on lower memory machines" (Virgil seems to have done a range of comparitive tests). Without sane guidance as to what is and is not the right value we are not in a position to change it even if we did have a knob.

Personally I have found desktop lumpyness has been most affected by the sched autogroup changes than anything for swappiness.
