Why even accept ramdisk=<size> or limit the size at all? Since the new ramdisk won't waste space unless it is actually used, there is no reason to have the parameter. If the intent is to protect against root doing 'cat /dev/zero >> /dev/ram0', then you won't protect a 4 MB system anyway. With this one, I think root should be allowed to shoot himself in the foot (with water-gun until foot rots off). Real protection would be to limit total ramdisk+mlocked memory to 75%.
