I spent about a month trying to figure this out, with no luck. It seems the best bet is to use DXTEX to create DDS files, which you can load directly onto DirectDraw surfaces. DXTEX also supports command line operation (ie., give it an RGB bitmap and an alpha bitmap from the command line, and it will save to a 32-bit DDS). This command line operation makes it possible to make animations of DDS files quickly, using batch processing.
