When a driver uses a crtc during device detection, the scrn has not yet been configured and virtualX/virtualY are still zero. This caused the X server to try and allocate a shadow frame buffer, which couldn't work. Detect this by checking for zero virtualX/virtualY values. Signed-off-by: Keith Packard <keithp@keithp.com>
