How to get a lower boot time in eee?

Question

I've managed to lower my boot time to 14 seconds on the asus eee, but I know it can get lower that that... Apart from recompiling the kernel (which I intend to do last), can you suggest anything else might help?

I see that you mention milliseconds again, how exactly do you count these milliseconds? Since my last message, I've tried other I/O schedulers and three out of four get the same result. I believe that there IS a difference among schedulers but since bootchart displays the results in seconds, I can't compare them. If you could just tell me how you count in ms I could compare them and see which one is faster at booting the eee. In case you're wondering, noop is the slowest, requiring 16sec to boot the eee while cfq, anticipatory and deadline require 14sec according to bootchart.
I'm talking about "loading" modules, not the full-boot time..
After turning on the PC, there will be shown on the virtual terminal the time taken by Udev to load all modules.
as you can see
