I'm pretty new to Fedora, so forgive me if I'm way off, but I would check
your Xorg configuration file.  While setting up the dual-video card display
on FC5 that worked a week ago in FC3, I found that my xorg.conf file
determined if the computer would freeze on me.  Upon loading inittab,
though, the computer would also freeze the keyboard and the ability to shut
down by quickly pressing the power button on the tower.  Fixing the problem
was only a matter of reconfiguring xorg.conf, which I accomplished by:
1. Boot the computer from the first install disk, and type "linux rescue" at
the prompt
2. Find your root drive in the /mnt folder, named...I forget..."sysvol"
maybe
3. Remove the "/etc/X11/xorg.conf" file
4. I got tired of the bootdisk, so I changed inittab's line 18 to
"id:3:initdefault:" instead of "id:5:initdefault:"
5. Reboot,
a. If you didn't change inittab, it will probably try to make a new
xorg.conf file - it did for me.
b. Otherwise, you can mess around in the bash or whatever and see if it
continues to freeze, and you can type "init 5" when you feel like testing
the GUI.
Two other things that froze my system - my CPU was overheating without
Powersaving mode, and my USB network device likes to lose connectivity and
make a few things cry.  Hope my problems let you think of something.
