   This is just a guess....  The main change (that I know of)
  was in 2.6.24 to support “tickless idle”.  I just finished(?)
  fighting the battle to get the system timer to run reliably
  (discovering, in the process, a (minor) bug with our SoC ;-\ ).
  I've a meeting in a few minutes and so no time to write down
  any details (now), but hopefully Ralf or someone can either
  fill you in or point (both of us) to some doc.
