Nvidia module will not load after update [Solved-but don't get too excited]

[Adeswas]

Running an old p5 with an nvidia gf4.  PCLOS 2010 all latest upgrades as of today.  Before upgrading, everything was fine, KDE worked well--everything worked well!  After update no GUI.  The system will eventually give me a command prompt after a long (20 min.) delay during boot. I ran lsmod, no nvidia drivers were listed.  Tried modprobe nvidia 96xx and the following is returned:

Fatal: Unknown symbol in module, or unknown parameter (see dmesg).

Dmesg reveals:

The nvidia geforce4 ti 4600 gpu installed in this system is supported through the nvidia 96.43.xx legacy drivers.  The 256.53 nvidia driver will ignore this gpu.  Continuing probe...  No nvidia graphics adapter found!

So obviously the wrong nvidia driver is loading, which doesn't show in lsmod, and is blocking the correct driver from loading.  Any ideas would be most welcomed.  
PS: I have done my best to RTFM but am either blind or stupid--possibly both.
Thanks very much

Can you boot in VESA mode?  If so, boot up, run Synaptic, and uninstall the other Nvidia drivers.  Otherwise the advice still stands - remove the drivers you don't need and just leave the one you do.

I had a motherboard with onboard S3 video that wouldn't enable 3D acceleration or otherwise behave properly until I stripped out all the drivers I wasn't using, regardless of manufacturer.

You can change the device driver in the /ect/X11/xorg.conf to nv.

Section "Device"
    Identifier "device1"
    VendorName "nVidia Corporation"
    BoardName "NVIDIA GeForce 6100 and later"
    Driver "nvidia" 
    Option "DPMS"
    Option "DynamicTwinView" "false"
    Option "AddARGBGLXVisuals"
EndSection.

That should let you boot into KDE or whatever environment your using. Than you can install the driver you need from synaptic.

Got a command prompt so removed all nvidia drivers.  Reinstalled nvidia96xx.  NFG.  I am now reinstalling PCLOS.  I'm in the process of updating right now, so we'll see what happens after the update...
Fingers crossed.  Thanks for the help.  I'll return with the highly anticipated results in awhile

Problem solved after reinstalling pclos 2010.11 and updating from there.  Not great, but it worked
