Exactly what the thread title says - in recent years, southbridges have been stagnating and haven't really been very interesting. You know something is wrong when the biggest innovation of 2007 was probably native support for using NAND as cache! I'm sure some will disagree with that specific example, but you get the point.
The main thing I can think of is RAID5 (and maybe even RAID6) hardware acceleration, personally. Looking around, I could find a die shot of an old IBM product that had it and it didn't look so big, so it certainly shouldn't be on a 55nm process! So, what else could be interesting to integrate (or invent and add) to modern southbridges, if anything?
