The issue is likely related to the driver supporting your nvidia “go” chipset (new feature: 'nouveau') or to the monitor parameters (automatic detection and parameterization is a also new feature)
Try first to boot in run level 3 in order to verify that the issue is due to the nvidia support.
When grub starts, press any key you want to make the menu appear then press the e key to enter in edit mode.
Using the arrows, position the spot at the end of the line beginning by kernel and add 3 (the number).
Validate by enter and boot.
If the run level 3 does properly start, the issue deals with the nvidia support. Type the following commands:
$ su -
$ password:
# setup
-> Xorg to parameter
# init 5 -> to try to launch the graphic environment
1. type setup and go through some menu options to disable SELinux
2. in the XWindows configuration change the driver to vesa
3. start run level 5 from a terminal type -/sbin/init 5
4. This will give you 800x600 resolutions. login and enable livan-devel repo
5. yum -y update from a terminal
6. yum install kmod-nvidia
Also I found issues with selinux and your specific laptop as well. During the install disabled it as well.
Here is a great guide for fedora 7 setup.
A problem I have seen for most people is that they add freshrpm and other European repositories with US repositories. This is a bad thing. If you can get a fresh install and do this setup, with new kernel and kmod-nvidia your problems should be fixed.
