dynamic tick patch and slow boot

One issue, apparently, is that systems running with dynamic tick tend to boot slowly, and nobody has yet figured out why.
I know the CELF group has done some detailed studies of boot time (an obvious point of interest for CE devices), and I thought LWN covered some more generic kernel boot-time studies--with graphs, even--a year or two back. Has anyone done something like that yet? More precisely, is the slowness evenly spread across all kernel subsystems, or is it confined only to those related to HW probing, or ...? That seems like an obvious first step to understanding the nature of the problem.
