Modern flash chips support on the order of 1,000,000 write cycles, so this is not such a concern anymore. There is no reason why we shouldn't put a filesystem on a flash card. A better choice might be the flash disk cards from SanDisk and others, since they do have an ATA interface and look like a small ATA drive to the pccard code. Unless the linear flash cards are a LOT less expensive, there isn't a lot of reason to do all the extra work. -- "Where am I, and what am I doing in this handbasket?"
