I hacked fs/jffs2/super.c and fs/jffs2/super_v24.c. Only the v24 got 
compiled. I guess this is because my kernel is 2.4.21.  I had to also include 
ramdisk in the kernel as it was previously missing ? Does this effect MTD ?
This mounted rw.

-bash-2.05b# ls -l /dev/ram2
brw-rw----    1 root     disk       1,   2 Jan 31  2003 /dev/ram2
