You can do it if you have another bootable optical handy.  I've had to
do this to repair a damaged root partition on an optical.  

1) boot with the good optical to single user mode (bod -s)
2) /etc/disk -e /dev/rod0a
3) stick in the blown disk quickly (you have about 30 secs before it will page)
4) run /etc/fsck on the blown disk and fix it.

This is assuming that you have very generic boot disks and the swap file
is at the same place.  You can't do this to a non-bootable disk.
(hopefully you don't have to do this at all :-)
