If someone wants do that, sure. There just might not be something like the
"average hardware". E.g. on my T61 the USB stuff seems to contribute
significantly to the boot time (maybe because the BIOS doesn't want to let
go of it?), on another box it might be some other piece of "average
hardware".
But really, just plaster the kernel's main2() with time measurements and
test on a lot of different hardware. Maybe a better distribution of the
stages presents itself. We could even add more stages for the boot script
(at least up to the point when the app server is started), if necessary.

That should be possible. Basically the initialization thread would need to
report its progress more often (after every line) and another thread would
need to monitor it.
