Just an update: I've been messing around with my R4i Gold 3DS and it seems that the problem is definitely an issue with the card and not with the metroid icon firmware. I found this out by downgrading to a firmware prior to metroid icon and tried upgrading to the latest from that firmware with no luck. I'm now currently sitting on metroid icon firmware again.
I have a feeling that we're probably not going to see a firmware fix for this bad batch of Rev C's. If you can, I would try to ask for a replacement. Nds-card has already shipped me mine, thankfully
