Yeah, that's how I read it too. It might be harmless; I'm really only concerned with it because I wonder if it's a cause of some of the other problems (like maybe the screen flicker issues would go away if the X server wasn't having to do something unusually slow with the frame buffer -- I guess a 3520x1200x32 fb is only 128MB or so, but still) The "Cannot get VRAM scratch space" part is more of a worry, honestly; that seems like it might mess up things the firmware is doing. zw -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
