You will need to use something like mplayer to use the OUT function on that card. You should read the DOCS from Mplayers website:
www.mplayerhq.hu
This will explain how to do it. One thing to note is that you will need to have the "out" device plugged into the card during bootup to initialize the out function of the card, aka, VESA.
Good luck, and after reading the docs if you still have problems I will be happy to help. I have an ATI Rage Fury Pro, and it also uses Rage 128 drivers. So the cards should actually work the same in practice.
Cool
