You could just use the old gui. See gui/newgui.cpp (look at
DISABLE_FANCY_THEMES, which doesn't exclude the new gui theme code
though). Disabling buffers would slow down it too much (it's even too
slow on eriks p3 450 then), also the only buffer the gui uses is a
separate screen buffer (and a surface of the current screen) that
should be: w*h*sizeof(uint16). The special screen buffer is also not
allocated while there is no gui open.
