I figure we can use this thread to brainstorm a way to get the SD Card slot to start working in OS X.
The slot is a JMicron device. The good news is that it DOES work in Linux. Linux drivers have been ported to OS X in the past, such as the Tulip driver, which supports some network cards (I think I have an old Linksys that uses the Tulip driver in OS X on my main machine). So the first step might be getting the source for the driver extracted from Linux. Then we're going to need a serious guru to figure out how to compile it for OS X.
I wonder.. If the Linux driver has already been ported to BSD? Or if there's already a BSD equivalent? That would make it much more close to plug and play.
