This appears to be a problem for practically all consumer-available flash media. They spend a lot of effort trying to hide any flash properties from their users. And while this is a decent strategy for FAT, ext3, ntfs and similar, it is actually very inefficient for a flash filesystem. After talking to several manufacturers, most seemed to be fairly open-minded towards supporting an alternate interface with raw flash access. So much for the good news. Bad news is that such an elternate interface still needs to be defined.
