I think the 9500 is like my s900 in that it relies on a PCI card for video. I also think that the original poster said he was using an IMS TwinTurbo 4MB card. I have success with my machine by setting the OF ouput-device to /bandit/IMS,tt128mb. You can use an 8MB card with /bandit/IMS,tt128mb8, but the OF text output is split by vertical bands of nothing (console works though).
