From the Software-RAID-HOWTO:

  2.5.  Swapping on RAID

  There's no reason to use RAID for swap performance reasons. The kernel
  itself can stripe swapping on several devices, if you just give them
  the same priority in the fstab file.

  A nice fstab looks like:

  /dev/sda2       swap           swap    defaults,pri=1   0 0
  /dev/sdb2       swap           swap    defaults,pri=1   0 0
  /dev/sdc2       swap           swap    defaults,pri=1   0 0
  /dev/sdd2       swap           swap    defaults,pri=1   0 0
  /dev/sde2       swap           swap    defaults,pri=1   0 0
  /dev/sdf2       swap           swap    defaults,pri=1   0 0
  /dev/sdg2       swap           swap    defaults,pri=1   0 0

  This setup lets the machine swap in parallel on seven SCSI devices. No
  need for RAID, since this has been a kernel feature for a long time.

I was going to until I read this. :)
