Hmm. I modified S07bootchart to wait in a semi-busy loop until a
process called gnome-panel appears. Probably in the -none case since
gdm starts last, gnome-panel is picked right after it starts so it
doesn't show up.

Well, the problem is defining what is actually boot length. While the
actual boot time may be longer, it certainly feels a bit faster
because gdm starts earlier. Do you have an idea on how to accurately
measure the boot time?
