/dev/dump isn't supposed to point at a disk.  It's just a misc device
which supports the ioctls used to configure LKCD.  That's why you're
getting this error:

/dev/vmdump is automatically set up as a symlink to your first swap
device (by the /sbin/lkcd shell script, when you run "lkcd config"), so
leaving DUMPDEV pointing at it is the easiest way to dump to swap.

Yes, it gets built in init/kerntypes.o as part of your kernel build.
