Flashdisk failing at rtems_fdisk_compact() - shouldn't I get a device node regardless?

I suspect so. The flashdisk at the block device layer lets any file 
system work on a flash disk and JFFS2 expects to operating at the flash 
device layer where the rtems_fdisk_driver_handlers operate.

If this works out, and I see no reason for it not to, it might be a good 
idea to move these handlers and the interface into something different 
to avoid confusion.
