That won't work.  VGA doesn't support 640x480 in 8 bits.

So try putting this line in your code:
   set_gfx_mode(GFX_AUTODETECT, 1024, 768, 0, 0);

GFX_AUTODETECT will try all the graphics drivers and pick one that
fits.  What version of Allegro are you using?  (You should use 3.9.32
from the Work in Progress page.)
