  Yes.  You need mfs support in your kernel (this is only an issue if
you have compiled your own kernel, mfs is turned on in the GENERIC
kernels).  Usage is as simple as adding something like

  swap  /tmp  mfs  rw,-s=<SIZE> 0 0

  to your "/etc/fstab".  This example is for a ramdisk "/tmp" directory
of <SIZE> blocks (one block is 512 bytes).
