Thanks all. I am typing this message on my A7N266-VM running RH8.0. Some notes,
shall use LILO;
shall use text mode before any video working;
for video, make sure device driver names match;
for sound, may need to add "modprobe nvaudio" in /etc/rc.d/rc.local;
for nvnet, it worked for me first time;
went with tarballs.
Happy NV Linux!
