There's probably another change you should supply. The check for 
ALLEGRO_VRAM_SINGLE_SURFACE was applied like this:

#ifdef ALLEGRO_VRAM_SINGLE_SURFACE
   if (set_gfx_mode(c, w, h, w, h * 2) != 0) {
#else
   if (set_gfx_mode(c, w, h, 0, 0) != 0) {
#endif

However, that won't work if someone's trying to use triple buffering and 
it may improperly fail if someone's using dirt rectangles or double 
buffering. I think it should be changed to this:

#ifdef ALLEGRO_VRAM_SINGLE_SURFACE
   if (set_gfx_mode(c, w, h, w, h * 3) != 0 &&
       set_gfx_mode(c, w, h, w, h * 2) != 0 &&
       set_gfx_mode(c, w, h, w, h) != 0) {
#else
   if (set_gfx_mode(c, w, h, 0, 0) != 0) {
#endif

Forgive me for not supplying a diff, but I accidently overwrote my local 
CVS copy of demo.c. One more thing.. I personally think it's high-time 
someone removes the MIDI driver check hack. If you're gonna use the 
sample, use the sample, or else use the MIDI. You don't do something 
like this in normal games so doing it here is very bad design, IMO. 
Especially for those that try to learn by example.
