No s-video on ATI X300SE on 11.1

I just installed OpenSUSE 11.1 on a computer with an ATI X300SE (PCIe, vga and s-video output), connected only via s-video to a TV.

Half-way through the boot process, the tv goes blank (almost exactly when the white progress bar has reached the center).

BIOS and the whole installation had video. I get video also in fail-safe mode.

Any help on how to make this work would be appreciated!

When I plug in a VGA monitor, I get video. In Applications > Configure Desktop > Display, there is an S-video group but all options are greyed out…
