Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Fedora 9 is an upstart system and you will find all the runlevel codes in /etc/rc.d and the rc.sysinit starts it up.
Running a /chkconfig --list/ should tell all what you have on in runlevel 3. Check google for an HOW-TO that may be more complete.
Dims, I used a serial line console for a couple of years but used SSH to actually control the server. I couldn't get the machine to boot without a console and I used the console only to boot. I don't remember ever seeing color (or needing it) as I was just bringing up a server on our local net. I'm pleased you were able to sort it all out. Perhaps the termcap or terminfo docs will be of assistance for color. google is our friend.

Most machines will not survive the POST (power on self test) if certain facilities are not present. You will normally hear a beep code from the motherboard that will decode what is keeping it from starting. Unless you have a setting for bypassing the graphics test in the bios, the motherboard will stop. The easiest fix is to put in the cheapest old graphics card (doesn't matter what kind since you will not be using it) you can find and just go forward with the boot sequence.
Initially I was also thinking, that this was the POST problem -- i.e. system might not loading due to graphics card absence.
But this suggestion was discarded.
I have removed all familiar (for me) graphics options, including GRUB menu, and got boot messages via serial link. I see, that kernel is loading, hence BIOS is configured correctly and computer IS able to boot withoug graphics card.
But the loading process is still hangs now, although this happens later.
Assuming it dies in the /etc/rc.sysinit stage, you could follow its progress through the process. Assuming your default runlevel is 3, run a / ls -al /etc/rc.d/rc3.d / to see just what is called and when. rc.sysinit calls them in order; first the Knn (Kills) and then the Snn (Starts) You can compare the point where it dies with this schedule and see when and what process made it die.
What are your kernel parameters in the GRUB configuration?
Dims, the reason I asked about the GRUB kernel parameters is that I don't know how your serial console intreprets the boot process. info grub, in Section 7, addresses the serial console and you may need the --dumb option to describe your terminal. I'm sorry -- its been quite a while since I used the serial console terminal and I just don't remember how I had it all set up. I did keep a graphics card installed as it wouldn't boot without it. But maybe it wasn't required. Getting old is hell on my memory but it does have some good effects also; I also forgot the disappointments we all experience in life.
