Namely there are two problems. One is that sometimes card detection on xD controller stops working. That is it doesn't respond to insert/remove events, and suspend to ram just updates that once. Granted I wrote this driver, but it appears to work without richoh-mmc. Another problem that is unrelated to xD is that sometimes sdhci conroller issues an interrupt storm, and does so until its driver is reloaded. At that point it refuses to load with missing voltage levels. I never seen these without ricoh-mmc pci quirk. Both problems are semi-rare. So just one question, did you see these problems? Do you have a clue on how to proceed?
