I originally tried the register_mtd_user() route, but in the case of 
partitions it is passed the "slave" struct mtd_info, while only the 
"master" whole-device struct has been filled in with chip-driver-private 
info (and only mtdpart.c knows how to map the slave back to the master), 
so that would need some ugly tweaks as well...
