I just installed Fedora Core 1 on my A7N266-VM nforce2 system.
I downloaded the nforce drivers from Nvidia. The package comes with
audio, nic, and agp drivers but my video and audio seem to work fine
with whatever gets setup during installation of FC. So, I compiled and
installed the nvnet driver for the integrated nic.
I was having a problem with mouse lag (jerkiness) whenever there was
network activity. It occured both in X and in the the text console.
After some research I found that there is a driver option called
"optimization" for the nvnet module. The default setting is "throughput
optimization" and the other setting is "CPU optimization". I found that
by switching to "CPU optimization" that the mouse problem went away.
I added the following line to my /etc/modules.conf file...
options nvnet optimization=1
in addition to the line which was already there (added by kudzu, I guess)
alias eth0 nvnet
I hope this info is helpful to someone.
Thanks for this information.
It would be interesting if on your system the mouse and the ethernet
card are sharing the same IRQ (cat /proc/interrupts).

The problem occured with both a USB mouse and a PS/2 mouse. eth0 is on irq10. The usb-ohci driver is also on irq10 but the PS/2 mouse, when it's plugged in, is on irq12.
I'm also having another problem with the nvnet driver. Occasionally, when I initiaite network activity (click on a hyperlink, enter a URL, etc.), I get a complete lock-up. Keyboard goes dead (no response from capslock lights even) and mouse goes dead. Fortunately, I've found that I can bring the system back to life by unplugging the network cable and then plugging it back in.
This is all very odd, I'm going to disable the integrated nic and install a Linksys nic and see if the lockups continue.
