Hmmm, to use fullscreen DGA mode (xmame option "-x11-mode 1") you need to 
have root permission ! Note that "setuid root" executbales are normally 
considered *dangerous*. But if you still want to do so, you need to "chmod +s 
xmame.x11" (as root !). A "normal" user should then be able to use fullscreen 
DGA mode as well. 

Look at the messages produced by xmame.x11; if it says something like

rene@linux:~ > /usr/local/bin/xmame.x11 -x11-mode 1
DGA requires root rights
Use of DGA-modes is disabled
...
...
X11-mode 1 not available, falling back to normal window code
...
...

then this is exactly your "problem" !

BTW: If your graphics card and XFree86 (which version ?) drivers are capable 
of _good_ GLX acceleration (OpenGL), I'd recommend using the xgl target 
instead !

Hope this help,

Rene
