A simple name based udev rule could symlink ps3vram to mtdblock0, so an upgrade will not break existing setups. > +obj-$(CONFIG_PS3_VRAM) += ps3vram_ng.o Please give the driver the obvious name "ps3vram", that way upgrading will be smooth. I see our old mtddriver does not have modalias support for autoloading. Hopefully the new driver has this feature.
