Hi,
I'm also trying to get a Leadtek card with the GeForce3 Ti 500 to work
under 2.2r4.
I couldn't get it to work under XFree3.3 (would only display in 640x480
8bit) so I upgraded to XFree4.1.0 with Nvidia's own drivers.
I can now get a decent resolution but X is acting very weird, the system
locks up every now and then for 5-10 seconds (the mouse cursor
dissapears when that happens) and then returns to normal.
It's obviously not happy. :o)
The machine is a dual proc running 2.4.17 but I removed smp support from
the kernel to check if that was an issue with the video drivers.
I know that won't help you much but maybe we can share experiences.
