I was able to work around this problem by doing these steps to exploit a
feature of Allegro's blit() function:

1.  Use at least a 15-bit or higher video mode.
2.  For every image that you load, have a 8-bit bitmap (create_bitmap_ex())of
the exact same size (or bigger) of the bitmaps that you want to load.
3.  Set your palette for whatever bitmap you are loading.
4.  Load your bitmap into the 8-bit bitmap.
5.  Blit the bitmap to the desired high color bitmap.
Repeat 3-5 for each bitmap.
