If you're talking to me, then no. The problem I'm beefing about is that the 64bit drivers in a 64-bit install - when running a GeforceFX-series card - get unspectacular performance, lag, jitter, spike, freeze, lockup, hang, and crash for no reason that anyone has been able to discern. I think my fruistration with the drivers is understandable.

Its seems to work fine on VIA chips, in both 32 bit and 64 bit mode.
I am looking to buy an athlon64 in a few days and am having trouble deciding between Gigabyte K8N and ASUS K8V.
I was waiting for nforce3 250, but other than pci lock which remains to be known. The rest of the features are a non issue for my needs.
So far I have tried with both VIA and SiS and get no AGP acceleration. With Mandrake and a 2.4 kernel and Gentoo and a 2.6.3 kernel. With Gentoo and no AGP acceleration I still get over 5000 fps. Sure would be nice to have it work correctly!!

I for one CAN get AGP acceleration - with full 8x speed, fast writes, and all the frills. My system is not stable with AGP enabled, fancy features or no; I get frequent lockups in X, which generally require a complete reboot to regain control.

I have now noticed that the awful lagging that also happens when I enable AGP, still happens under some circumstances when running an intense OpenGL program such as Celestia. Celestia's performance on a GeforceFX5200 without AGP appears very good, though I can't benchmark it, but if I am so silly as to try to move the window, the horrible jittering and lagging starts again, such that I have to control-alt-F1, wait two minutes for it to respond, then 'killall celestia' from console.

Sounds like maybe I should be happy to not have acceleration.

I wouldn't call it "acceleration" anyway. 2D redraws happen considerably faster, but 3d performance is actually much worse - though it has higher average framerates, it's so jerky that it doesn't really matter, plus the aforementioned lagging where any other running application gets horrible refresh rates and/or redraw times and are extremely slow to respond to things like mouseclicks.

Just upgraded to 2.6.4, and.. yup, still has it.

Playing around with kernel boot parameters.. iommu=off or iommu=merge seem to give somewhat better cooperation; I can run xmms with equalizer and celestia at the same time without xmms grinding to a halt, but something's still obviously gumming up the works, since celestia is very very jerky. Quicker to respond to input events, but very jerky video.

I just installed gentoo64 and all is well ut2004demo runs fine a little faster than in 32bit mode.
Have you turned off acpi and apic? both of these dont play well with nvidia drivers.

Works fine Here in both 32bit mode and in 64bit mode.

I'd tried that before to no avail, but not with 2.6.4, so I'll try again.

...nope. Disabling acpi and apic causes the nvidia driver to simply not detect any agp at ALL. The output from /proc/driver/nvidia/agp/status is worrying... not 'disabled' or anything like that - just nothing at all. I'll try the other two combinations, and see how they work...

Nope. Performance still supremely sucks with every combination of noapic and acpi=off.

When I disable acpi, the nvidia driver can't detect agp at all, so I'm left with poor performance in general, but at least it's not extremely jerky. Disabling apic still allows it to find AGP, and seems to give somewhat better performance, but whenever anything 3d is running, it runs extremely jerkily, and 2D performance gets flushed down the toilet.
