Update - the above numbers were with an older version and with the cache
partition located at the very end of the drive (hence being a lot slower
than the root partition at the front). The fcache boot takes 33 seconds
now, from the kernel starts loading to the kde login has finished.
Probably 5 seconds of that time is device probe and network setup (dunno
why the latter is still sleeping so much, I disabled dhcp for this test
to avoid waits (for both fcache and normal boot, of course)).
