I run a self-compiled kernel (3.7.4) on my F17 box, I've removed all the 
modules I don't need. I did it because I run Gnome on a 1 GB box and 
need all the memory I can get. I also don't run any services except 
dbus. Gnome still loads a crapload of stuff that I can't remove. My idle 
memory usage (in Gnome) is 130 MB.

It boots at exactly the same speed as the Fedora kernel. Disable all the 
services that you can, and things will boot quicker, but not that much 
quicker. Systemd does a great job of running startup jobs in parallel.  
Because I have an encrypted home, boot time doesn't mean a lot, it takes 
me longer to type the luks password.
