:bump:
I figured it out. Thendar was having the same problem with the same card (ATI Rage 128 Pro), so hopefully this will help him.
When installing X, I had to set the vendor to fbchips (think that's the name...i know it's the only one that starts with "fb") during Debian Configuration for xserver-xfree86, then used all the default settings. Then, as root, I ran xf86config and selected the driver for a Rage 128 compatible card.
Works great now. Thanks everybody.
