By any chance are you using the radeon graphics driver?  When you issue
'su -c init 3' from a xterm, does X get killed?

I had a similar experience.  I blamed the radeon driver, but found that
booting with the kernel param 'nohz=off' greatly reduced the CPU time
eaten by X.  (I don't have a 'root cause' for this one, sorry)
