AFAIK swapped processes in top are shown in lt + gt signs (braces):
  1382 root         1   5    0  1380K     0K ttyin    0:00  0.00% <getty>

from `man top`
COMMAND is the name of the command that the process is currently 
running (if the process is swapped out, this column is marked "<swapped>").

In `ps` output in column state: W - The process is swapped out.

You can get a list of swapped processes by this command:
ps auxwww | awk '$8 ~ /.W.*/ { print $0}'

(tested on FreeBSD 6.2 & FreeBSD 7.0)
