Interesting question... The actual swap configuration from the config file
goes into /sys/{MIPS/}swapvmunix.c, and puts hard coded major and minor numbers
in a table. You get the "No such device" if you're adding an area already in
use, but might also get it if the partition wasn't allocated or if you don't
have an appropriate /dev entry for the device - it may be that swapon makes
some references to the /dev entry before issuing the "swapon" system call.
