RHEL has it, not sure about Fedora, F17 doesn't install with my partition layout (openSUSE does though ;))
I installed Fedora 17 in a virtualbox to test further. I am quite impressed with the startup speed, but I also looked carefully at the Plymouth behavior. And what I can see is similar to what we have on openSUSE, namely: 1) There is a small flicker happening between Grub2 and Plymouth. This is a shorter flicker than on openSUSE, due to the fact that Fedora is initializing deviced inside the Plymouth startup scripts. 2) There is a black screen between Plymouth and KDM. However the question arises if this is indeed a flicker/black screen, as that there is a mouse pointer visible which indicates that KDM is loading.
Can this black screen have it's origins on VT switch from 1 to 7 ? Everyone else moved X session to vt1, I'm pretty sure there's something behind it, maybe asking Strode would be a good idea, of all, he's the one who probably knows it.
As indicated above also Fedora has the small flicker in between Grub and Plymouth. Working on VT 7 doesn't influence this, but it points all to the fact that as soon as Grub starts loading the initrd, it's graphical screen is disabled and then it waits until Plymouth starts.
If I recall correctly from the docs in 2010, plymouth should exit without refreshing the screen (thus keeping the last image on the display) and X needed to be restarted with a switch (-r if I recall correctly) so it doesn't refresh the screen in order to keep the 'frozen' screen image from plymouth exit until GDM loads up.
It seems that the question is more how fast can GDM/KDM loads its graphical screen. Maybe an idea would be to see if GDM/KDM can kill plymouth at a later stage, but I am not sure about that.
