To include an embedded alpha channel, the server would need to advertise depth 32 windows with RGB masks set to leave 8 bits for alpha. As far as I know, no-one has made the necessary changes to add depth 32 support to XFree86 X servers. The pixel format (bpp) is irrelevant here, aside from needing to be no smaller than depth.
