What I ended up doing so that I could run 5.2 on a couple of my "all RAID5 all 
the time" servers was this:

1. Create a UFS filesystem on the "swap" partition and mount it noatime,sync
2. Use dd to create the biggest file possible on the new filesystem
3. Use swapfile="/swap/bigfile" in rc.conf, which uses an md device with vnode 
backing and enables swapping on it.

It's a massive hack and there is probably a performance hit, but it seems to 
work...
