I think there are issues on Eye-Fi's end, and they affect more than just geotagging. I just moved 200+ RAW+JPEG pictures (over 400 files total) from my card to my computer, and only ~120 of them have been uploaded to my Picasa account. My laptop is showing that it's still trying to transfer the JPEGs to be shared, but it doesn't seem to be getting very far with any of the remaining pictures.
My cameras: Nikon D90, Panasonic ZS7
My Eye-Fi: 8GB Pro X2
