Well, there is mfs, which is a DOS FAT that has had an unfortunate
collision with logged file systems and I regret to say that there were 
survivors.  One could use lfs if it worked since it tries to avoid
writes to the same page over and over, which is what kills normal
flash cards.

Having them available as at least a read only device would be useful.
The pccardc interface is a pain to use :-)
