Well, I did have an idea. First, the function would be named 
select_hardware_cursor. It would also be paired with a function 
set_hardware_cursor, to which you can pass bitmaps for the different 
cursor states (or NULL for system or Allegro default, depending on 
what's available). You would use it like so:
// Set default cursor types
set_hardware_cursor(CURSOR_POINTER, custom_pointer);
set_hardware_cursor(CURSOR_WAIT, custom_waitpointer);
/* etc... */

Then to use them:
select_hardware_cursor(CURSOR_POINTER);
foo();
select_hardware_cursor(CURSOR_WAIT);
bar();

And set_hardware_cursor would update the cursor in real time, so if you 
have CURSOR_WAIT selected, and subsequently change CURSOR_WAIT, the 
mouse would update on-screen automatically (useful for animated cursors).
These functions would also behave exactly the same for drivers where 
there is a real hardware (not OS) cursor.. except passing NULL to 
set_hardware_cursor would set it to Allegro's default cursor(s).
