I do indeed have an Ati card (a Radeon 9100IGP to be precise). I use
the open source drivers but I thought I had OpenGL support. Glxinfo
reports direct rendering is on, glxgears shows 800fps and I get opengl
menu transitions in Myth ok. Or is this unrelated to openGl vsync?

That would make sense. Would it e possible to run this at half the
PAL resolution? I suspect things would look quite bad though.
