Yes it sure does -- the original timings were with a 2.0.36 kernel. I 
upgraded that machine to a 2.2 kernel and did some timings (time
to load netscape on a freshly booted machine).

page-cluster   time
  1            10.62
  2             8.38
  3             7.07
  4             6.4
  5             5.53
  6             5.05
  7             4.78


I used a stopwatch so there is certainly some error in the timings.
