Another "me too". Last driver where overscan worked for me and my FX 5200 was 4363. 5336 does not overscan at all.
Bios revision is 04.34.20.16.00, I'm using a card made by Asus, and they don't have any bios updates for video cards on their website so that is the latest. I am running Fedora Core 1 along with a vanilla 2.4.24 kernel.
