Please try mtdblock, not block2mtd.
The latter creates an mtd from a block device, not the other way around.

For best performance (as a block device), I suggest creating a normal block
device driver. drivers/block/ps3vram.c may be a good start point. After
removing all PS3-specific code and just using memcpy(), not much will
be left.

when I'm talking to journalists I just say "programmer" or something like that.
