Have you looked at the lttng-omap tree ? It is based on 2.6.32-rc8-omap though. See http://lttng.org/content/download LTTng OMAP support prior to this one won't support suspend/resume and DVFS correctly. The LTTng version you have for 2.6.29 is possibly based on the "generic" timestamp support, which provides a 1 HZ accuracy, which is pretty coarse.
