As a data point I'm using this and dump-on-panic works just fine:

   thoreau 64173> grep swap /etc/fstab
   NAME=swap               none            swap    sw              0 0
   NAME=swap               none            swap    dp              0 0
   thoreau 64174> dmesg | grep -w swap
   [     1.843214] dk3 at ld1: "swap-rf1", 134234112 blocks at 12288, type: raidframe
   [     1.843214] dk1 at ld0: "swap-rf0", 134234112 blocks at 12288, type: raidframe
   [     5.743186] dk7 at raid2: "swap", 134233823 blocks at 128, type: swap
   thoreau 64175> raidctl -s raid2
   Components:
               /dev/dk1: optimal
               /dev/dk3: optimal
   ...

Cheers,
Simon.
