Sorry, I forgot to include that documentation... I'm using
2.6.20.14, and I was waiting until 2.6.22 stable branch reached at least
10 (I'm tired of regressions with all 2.6.x kernels, so I try to avoid
updating if possible).

I'll give it a try, then, but not before 2.6.22.10 at least.

Currently I have CONFIG_HZ_1000=y and CONFIG_HZ=1000, and no
tickless idle since that feature was introduced in a later kernel.
Probably the problem is the shared timer and I will have to use 2.6.22
kernel to have it if I dare upgrading ;))
Thanks for the information, Andreas :)
