and there's that conenctor on it, 30 pin or something... anyone know if it's any use to get an svideo signal out of it or something similar???

I thought that the 30-odd pin connectors on boards like this were for DVD expansion. I have (but not using at the moment) an ATI All In Wonder Pro (not the 128 version), and that's what it's for on those boards - even though virtually no-one supports it.
