I thought (am I wrong?) that blkmtd referred to using a block device as 
an MTD device.  Either which way, Jörn tells me that blkmtd is 
deprecated by block2mtd anyway, and only retained for boot support, 
which is pretty easy to do in klibc.

That certainly works for me.  Jörn indicated he's going to sign off on a 
patch to remove blkmtd, which will solve my problem.
