I found the solution!

In the missing directory /usr/src/nvidia-190.53 I manualy create adkms.conf file using the template of the janitor script (I didn't know that the nvidia installer doesn't provide a dkms.conf).
After that I was able to remove the module with dkms with: sudo dkms remove -m nvidia -v 190.53 --all 
After that, the dkms status was ok, with no occurence of nvidia.

I tried to install the nvidia 195.36.24 driver  from ftp with the janitor but after reboot, I got this message in dmesg:
[   21.562036] nvidia: module license 'NVIDIA' taints kernel.
[   21.562040] Disabling lock debugging due to kernel taint
[   22.121196] NVRM: The NVIDIA probe routine was not called for 1 device(s).
[   22.121199] NVRM: This can occur when a driver such as rivafb, nvidiafb or
[   22.121200] NVRM: rivatv was loaded and obtained ownership of the NVIDIA
[   22.121201] NVRM: device(s).
[   22.121203] NVRM: Try unloading the rivafb, nvidiafb or rivatv kernel module
[   22.121204] NVRM: (and/or reconfigure your kernel without rivafb/nvidiafb
[   22.121205] NVRM: support), then try loading the NVIDIA kernel module again.
[   22.121207] NVRM: No NVIDIA graphics adapter probed!

So I uninstalled the ftp driver with the janitor, reboot and resinstall the distrib driver (with the janitor too).
I got a new mismatch api between 195.36.15 (distrib) and 195.36.24 (ftp).
Maybe I should have check that just after uninstalling the ftp driver with the janitor, the nvidia.ko was removed from /lib/modules/2.6.32-22-generic/updates/dkms/, that's right?

It was the same initial problem but with different versions... So I uninstall the distrib driver, recreate the dkms.conf for 195.36.24, remove the module with dkms, reboot and reinstall the driver from the distrib with the janitor and now everything works!!!!

Thanks 

Christophe

Thanks, Raphaël.

> Did you not remove all the old nvidia driver stuff before upgrading?
no... I didn't know. I will not forget the next time! 
By the way, why I have to removre only the nvidia stuff and not the Norbert's sony module? What's the difference?

> Ok. First try '--force' and if that does not solve your problem
the --force option didn't help... your help will be welcome!

Did you not remove all the old nvidia driver stuff before upgrading?

The directory '/usr/src/nvidia-190.53' seem to be removed during upgrade
process. When nothing else won't work, you may always be able to
recreate that dir with the original sources but first try to remove it
with '--force':

sudo dkms remove -m nvidia -v 190.53 --all --force

Ok. First try '--force' and if that does not solve your problem, I'll
explain how you can recreate the removed source dir.
