I've ported NetBSD to Mesa Electronics 4C81 PC104plus SBC.  The storage
is 32MB/64MB bare NAND which holds BSDFFS.  Bad blocks are forwarded
by a preconfigured badblock list.  No MTD included.  Bootloader knows and
handles /netbsd.  The NAND block device driver allows writes.  It'd be likely
to get highly criticized but the decision was made weighing "the rootfs is
seldom written beyond configuration mods by administrators."  Software ECC
is always calc'ed and verified, block write is counted and recorded inside
NAND spare fields.
