I've added a screenshot (screen photo) of the GNOME desktop being stuck and unresponsive while running the ATI Radeon 4350 PCI on the K8 AGP host.
You'll notice this is the exact same symptom I get with ATI Radeon AGP cards on this host starting with kernel 5.4.0-48-generic and later (while that AGP card worked flawlessly on 5.4.0-47-generic), see #1899304 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1899304
On the K8 PCie host, the display goes off immediately at kernel launch, right after GRUB launches it, so there is absolutely nothing to see. If I'm right, the lockup is so hard the system does not run in background and I cannot connect through SSH (right, this is the same symptom I get with the Nvidia PCI card).
I don't have access to recent enough (GL 3) Nvidia AGP cards to compare symptoms with that GL 3 Nvidia PCI card.
