I haven't seen systems that boot in less than 6 seconds (and by

experience with common hardware.
At FOSDEM they demonstrated 2 seconds for kernel + userspace. Userspace
being GDM. The initialization of the presenter took longer than the
kernel+userspace bit, so they had to use a camera to actually show this.
The firmware on that laptop took about 7 seconds. As Lennart mentioned
elsewhere, new laptops must do less than 2 seconds to get that nice
Windows logo, some do 0.5 seconds.
So laptop booting to GDM in 2.5 - 4 seconds after pressing the power
button is realistic.

The demonstration is at the beginning.
