From my experience Dominions does support the 32 bit targas, but when using them you have to use the alpha channel for the background color instead of black (and I haven't figured out how to do the shadows). That being said, the 24 bit still seems easier to me, as it is much simpler to just color everything black then to painstakingly select the background and All and Only the background before converting to alpha, plus it tends to leave those unsightly black lines.
