Spettacolare!
Il problema era tutto nel settaggio dell'AGP
Kernel 2.4.6. Ho inserito
Option "NvAGP" "2"
Grazie grazie grazie... :P

in effetti:
There are several choices for configuring the NVIDIA kernel module's use of
AGP: you can choose to either use NVIDIA's AGP module (NVAGP), or the AGP
module that comes with the linux kernel (AGPGART). This is controlled through
the "NvAGP" option in your X config file:
Option "NvAgp" "0" ... disables AGP support
Option "NvAgp" "1" ... use NVAGP, if possible
Option "NvAgp" "2" ... use AGPGART, if possible
Option "NvAGP" "3" ... try AGPGART; if that fails, try NVAGP
The default is 3 (the default was 1 until after 1.0-1251).
You should use the AGP module that works best with your AGP chip set. If you
are experiencing problems with stability, you may want to start by disabling
AGP and observing if that solves the problems. Then you can experiment with
either of the other AGP modules.
You can query the current AGP status at any time via the /proc filesystem
interface (see Appendix M).
To use the Linux AGPGART module, it will need to be compiled with your kernel,
either statically linked in, or built as a module. NVIDIA AGP support cannot
be used if AGPGART is loaded in the kernel. It is recommended that you compile
AGPGART as a module and make sure that it is not loaded when trying to use
NVIDIA AGP. Please also note that changing AGP drivers generally requires a
reboot before the changes actually take effect.
