The SDL_SetVideoMode() error condition is easily triggered by a user by simply configure a guest with a host unsupported display resolution and attempting to enable fullscreen. Since the error is fatal, adding a bit of debugging help can't harm.
Sample output with this change: (qemu) Could not open SDL display (1280x1024x32): No video mode large enough for 1280x1024 The width x height might seem redundant as SDL also provides it in SDL_GetError(), but I believe there are situations where it is useful. I.e. if there is some other SDL error. Anyway, redundant information in fatal error messages has never harmed a single gerbil.
