No, it breaks ABI.

You are lucky because Brian already took care of this. You need to use
his MEMWRITE ioctl. Try my l2 tree (or take patches from that tree) plus
the "brian" branch of the mtd-utils tree. The idea is that the new ioctl
should get to mainline soon, and we'll merge the brian branch into the
master branch in mtd-utils.

My tree: http://git.infradead.org/users/dedekind/l2-mtd-2.6.git
(you can use it or pick patches from there)
MTD utils tree: http://git.infradead.org/users/dedekind/mtd-utils.git
(use the "brian" branch)

Of course we are interested to know if it worked for you. Brian is in
CC.
