On nokia900 the sound has issues and CPU usage is 100% with the SDL backend
when scalling the game to fullscreen
Using XV and MIT-SHM seem to improve performances:
With SDL:
SDL found mode:800x480x16
SDL found mode:800x480x16
SDL: Using a mode with a resolution of: 800x480x16
Initialized no effect: bitmap depth = 16, color format = RGB 565
info: audiodevice (null) set to 16bit linear stereo 44100Hz
info: sysdep_dsp: using sdl plugin
info: dsp: using timer-based audio
Average FPS: 16.623416 (988 frames)
With X11,XV,MIT-SHM:
MIT-SHM & XV Extensions Available. trying to use.
Can't find a suitable RGB format - trying YUY2 instead.
XInput: Initialization...
Initialized no effect: bitmap depth = 16, color format = YUY2
Clearing YUY2
Using Xv & Shared Memory Features to speed up
info: set to 16bit linear stereo 44100Hz
info: sysdep_dsp: using alsa plugin
info: sysdep_mixer: using alsa plugin
Average FPS: 23.254317 (828 frames)
The nokia900 has an omap SOC, that means that it can uses omapfb,
which support xv, so using XV improve the performances in the case
of the nokia900
And in the case where XV is not available
(XV disabled for testing purposes, still on nokia900):
XInput: Initialization...
MIT-SHM Extension Available. trying to use... Success.
Using Shared Memory Features to speed up
Initialized no effect: bitmap depth = 16, color format = RGB 565
info: set to 16bit linear stereo 44100Hz
info: sysdep_dsp: using alsa plugin
info: sysdep_mixer: using alsa plugin
Average FPS: 18.793345 (1267 frames)
Which is a bit faster than SDL.

Without that fix we have(at runtime):
xmame.SDL
error: compiled byte ordering doesn't match machine byte ordering.
compiled for MSB first, are you sure you chose the right cpu in makefile.unix?
on arm little endian
