: Yes.  I was in graphics mode (set using the GFX_AUTODETECT).  RIght after 
: graphics system was init., I called the function, and I get a GPF.

But did the call succeed? set_gfx_mode returns 0 on success, negative on
error. After calling it you should check its return value, and if it was
negative report the error stored in allegro_error.
