So this may be useful for something after all... For most graphics cards, the 32 bit mode doesn't use the extra 8 bits. They're just there to make sure everything aligns on a 4-byte boundary, to give better performance. Or at least this used to be true, and seems to be on my Matrox Mystique. I don't think there are that many consumer graphics card that make use of an alpha channel. Now, SGI stuff is another matter, as they IIRC have high end stuff that can use 2048 bits per pixel (don't ask me what they store in there, I don't know, I just read it somewhere), and they certainly have graphics cards with hardware support for alpha channels.
