Indeed there are several things starting during boot that we can probably
defer to on-demand.  Anything dealing with wifi or GPS for example, is just
a waste of load time and scarce memory until/unless actually activated by
the user, IMHO.

I had composed an email a couple months ago regarding memory consumption on
2008.8, but never posted it.  Among other things, I've noticed that hald
and offspring sometimes consume more than 15% of system memory, though
apparently (??) only watching for four distinct inputs?  And sometimes
gpe-scap lingers wasting about 9% of RAM.

But back to the subject at hand, when I disabled some services from
starting on boot (IE wpa_supplicant, gpsd, avahi) there was noticeable
savings on both boot time and memory usage.  I never followed up since my
FR went in for RMA at that time, and when I finally had one in-hand again
there was SHR, FSO, QTopia, Debian, etc to consider, each with slightly
different circumstances.  (lately I've been using FSO, before that SHR,
before that Raster+Frameworkd, with brief tests of 2008.x interspersed)
