LinuxQuestions.org - 1)nvidia installer freezes (psble prob w/ gcc?) and 2) can't change screen resolution

Sorry for the slightly strange subject title - I did my best!

I have two installations of Fedora Core 3 (off the same disc), on two different computers. I'm also having two different problems. So here we go...

First Problem -------------------------------------------------
1st Computer, "Neuromancer".
Mainboard: Asus A7N8X-E Deluxe (nForce2 chipset)
Graphics: Outboard GeforceFX 5200
Problem: Installed ok, nvidia logo appears on screen during boot up, and I have a nice damn nice framerate on Tux Racer. The only problem is, System Setting -> Display won't let me choose a resolution other than 800x600 or 640x480. Is there a way I can increase the resolution?
More:
The installation was succesful, so I won't post dmesg, install log, /sbin/lspci etc.
#uname -r
2.6.9-1.667

Second Problem ---------------------------------------------
2nd Computer, "Earth"
Mainboard: Asus A7N8X-VM (nForce2 chipset)
Graphics: Onboard Geforce4 MX
Problem: During installation, nvidia installer said:
ERROR: Unable to find the development tool
'cc' in your path. [Ok]
Installation has failed. [Ok]

I had this problem on Neuromancer and I remembered I solved it by linking cc... Unfortunately, I cannot remember where I linked it to, and google wasn't helpful then, or now. I did a
#whereis gcc
/usr/libexec/gcc
#ls /usr/libexec/gcc
i386-redhat-linux
#ls /usr/libexec/gcc/i386-redhat-linux
3.4.2
ls /usr/libexec/gcc/i386-redhat-linux/3.4.2
cc1

So in a blind panic I ran around "link"ing /usr/libexec/gcc/i386-redhat-linux/3.4.2 to various places such as /gcc, /cc, /bin/cc, /bin/gcc, /sbin/cc, /sbin/gcc, /usr/bin/gcc, /usr/bin/cc, /usr/sbin/gcc, /usr/sbin/cc, etc.

(I believe I may have used the command "ln -s", instead of "link", when I was working on Neuromancer.)

Anyway, I then tried the installer again. This time, it freezes on "Performing CC test with CC="cc".

More: dmesg and /sbin/lspci can be posted if nessesary.
#uname -r
2.6.9-1.667

Using: nvidia-installer ncurses user interface
-> License accepted.
-> No precompiled kernel interface was found to match your kernel; would you li
ke the installer to attempt to download a kernel interface for your kernel f
rom the NVIDIA ftp site (ftp://download.nvidia.com)? (Answer: Yes)
-> No matching precompiled kernel interface was found on the NVIDIA ftp site;
this means that the installer will need to compile a kernel interface for
your kernel.

If anyone could help me with this minor problem, I would be very greatful.
