So then sidebrnz's idea of the dead fan isn't the problem since the
6150 doesn't have a fan I think(? too wimpy). I have a 6100 Nvidia
on one of my AMD64 machines and it's fanless so I'm not sure about the
Anyway, I think you can quickly press Esc to get out of the graphical install
page and it opts down to the console "boot:" prompt, then use "linux text"
to install F8 in text mode. ASAP, you want to edit the /etc/inittab to make
the initdefault be 3 instead of 5 so it boots to multiuser text mode.
You might need to edit the grub.conf to comment out the "rhgb"
or probably better, use the grub edit option to manually remove the
rhgb and add "3" to the line so it goes to runlevel 3 without having
to deal with the inittab and grub.conf file since you only need to
boot a few times like this.
When you're done you can install the livna rpm as root from
the text console
The kmod-nvidia install should edit the /etc/X11/xorg.conf to have
the driver be "nvidia" instead of "nv" and it will use the
proprietary driver. All this assumes that your 6150 just has some
problem with nv that the the nvidia driver won't cause.
After the gui is working by manually starting it with startx,
then set the inittab 3 back to 5 so it's automatic.
