Sadly I think you are right. Fixing the nouveau driver, and particularly
for older cards, is an open-ended problem.
Officially Nvidia only supports the GeForce 7600 hardware in driver
version 304. But driver version 304 is too old for inclusion in Ubuntu
20.04.
A newer Nvidia card (and using the latest proprietary Nvidia driver)
would also have solved the problem.

Title:
Unusable graphics, nouveau + G73 (GEForce 7600)
Status in linux package in Ubuntu:
Won't Fix
Status in xserver-xorg-video-nouveau package in Ubuntu:
Won't Fix
Bug description:
This is an older card, but it worked well on ubuntu 12.x :)
Booting "Try Ubuntu" on 20.04 get the correct resolution and 2
displays, but the video glitches and shows all sorts of noise. It is
largely unusable (which makes filing this bug very hard).
Safe Graphics works in low-res.
The nvidia proprietary driver seems to not support this device any
more. I like this card because it has no fan (and I don't do a lot of
graphics-intense stuff).
