dmesg without the cpuidle patch: http://userweb.kernel.org/~akpm/dmesg-bad.txt
dmesg with the cpuidle patch: http://userweb.kernel.org/~akpm/dmesg-good.txt

there doesn't seem to be a lot of difference in the time handling, except
there are large changes in when things happen in the bootup sequence.
