Not true.  You can dump on any large enough disk device (at least for
sd and wd disks).  A swap device is just normally used because its
contents are disposable.

So, you also need a `swap on' clause!

Erm, `swap' is a no-op here.  Swap devices haven't been put in
swapkernel.c for a year ortwo .  The only remaining functionality of
`swap' in the config line is to enable `swapgeneric', and the only
remaining functionality of `swapgeneric' is to enable kernel support
for the -a (ask for root device) boot flag.
