Arrow Wrong pixel frequency

I have for several years not been able to use the nvidia drivers on my AMD64 system (FC7) as it won't start up.
When I do all the correct things - like constructing xconf - the system starts up in text-mode without any problem (and no errors) but as soon as it switches to the graphic display my screen goes blank with the message : " signal out of range". And when I go into the X-log it says that the pixel frequency is 350 Mhz. That is of course way to high as the system can max. use 150-200 Mhz (pixel clock frequency of the monitor is nowhere to found but the highest display frequency is 1289*1024 with HF of 80 KHz and VF of 75 Hz.
My video card is a nvidia NV18 GEFORCE MX4000 (as reported by the hardware monitor in Linux) and I am currently using the VESA driver that works correctly. However,
when I want to start certain programs I get the message "Xlib: extension "GLX" missing on display 0:0". Although the GLX module is loaded (see below).
The program I want to load is e.g. "wine explorer.exe".
My hope is that when I get the problem with the nivia driver solved this problem is also gone.
The installed - but not used - nivia driver is:
xorg-x11-drv-nvidia-96xx-96.43.01 (at least that is the name of the directory)
To minimize space I will give only the relevant sections of my xorg.conf:
Section "Module"
Load "extmod"
Load "glx"
Load "dbe"
Load "extmod"
Section "Monitor"
Identifier "Monitor0"
VendorName "IMAX"
ModelName "17N"
DisplaySize 337.9 270.3
HorizSync 31.0 - 81.0
VertRefresh 56.0 - 75.0
Option "dpms"

Section "Device"
Identifier "Videocard0"
Driver "nvidia"
VendorName "Videocard vendor"
BoardName "nVidia Corporation NV18 [GeForce4 MX 4000 AGP 8x]"
Option "AddARGBGLXVisuals" "True"

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 16
Modes "800x600" "640x480" "1024x768" "1280x1024"
SubSection "Display"
Viewport 0 0
Depth 24
Modes "800x600" "1024x768" "1280x1024"
One last clue: glxinfo gives also the GLX missing error and its output is not very dlear to me.

I hope somebody with more knowledge of the controls of the nvidia driver can tell me how to solve this problem.
