I tried replacing the Super I/O a second time but it ended up ripping up some PCB tracks. As best I can tell, the board has some kind of failure on an inner layer - or something more insidious - which I couldn't pin down. In the end, I ended up replacing the motherboard.Hey @philpem did you ever figure out how to fix this? I have a 1208,000 motherboard doing the exact same thing.
My gut feeling is the motherboard ended up flexing when I removed the floppy and IDE plugs - as the clip on that side of the motherboard had broken. Sadly that's all I've got, no definitive root cause of failure, and a board with intermittent IDE that seems to depend on how the board is pushed and pulled.
