I'm pretty sure XBMC takes advantage of it too. Can't play HD video without the RAM upgrade, but can with it from what I understand. At least I seem to remember having heard that before. I've modded a few Xboxes with solder mods but I wouldn't even dream of doing a RAM upgrade. The idea that I would EVER get each of the pins individually soldered, without connecting any of them together with solder is laughable. And once they are connected together I'd pull out the desoldering braid but I'd end up pulling the solder off like four or five pins which would have to be redone. I'd get two of them good, but then I'd connect the next to and go back to the desolder braid, etc., etc., etc., etc....
