Yes, linkstation and storcenter have to migrate to the "physmap-flash" 
platform driver. For now you can define in your .config

CONFIG_MTD_PHYSMAP=y
CONFIG_MTD_PHYSMAP_COMPAT=y
CONFIG_MTD_PHYSMAP_START=0xffc00000
CONFIG_MTD_PHYSMAP_LEN=0x400000
CONFIG_MTD_PHYSMAP_BANKWIDTH=1

(I hope the numbers are correct, just found them in my local tree, don't 
remember any more what exactly they configure, please, double-check.) And 
yes, it must be fixed in the mainline. I'll see if I find time for this, 
maybe tomorrow (actually, already today.)

Thanks
