You can hack up a SD DETECT signal easily enough. On my sd card reader (http://dl.dropbox.com/u/41900/Photo%2026-2-12%202%2019%2051%20PM.jpg), the 2nd pin form the top of the sd socket is SD DETECT, it just isn't routed anywhere, so i just solder a wire to it and use it as SDCARDDETECT. On sdramps, a similar hack can be done. i don't know the pin out of the socket used in sdramps, but "os1r1s" from #reprap has done it. You can ask him on irc for the pin out.
