I don't know much about the boot profiler, but likely, it can  
influence the time between kernel loading and starting X11 only. On  
my machine, a fairly recent dual core desktop, most time is used on  
the other parts: the vendor's BIOS screen, Grub waiting a few seconds  
for possible user input, X11 and Gnome launching.

Nevertheless, a gain of a few seconds is great, considering the boot  
sequence (hopefully) remains stable and it's a gain on each of  
millions of computers.
