Some ideas:

1) You can run 32-bit applications on 64-bit FreeBSD (and / or set up a 
32-bit jail)
2) You can try booting a snapshot of 9-CURRENT and see if it helps. I 
think I saw some commits that could have fixed this problem. As far as I 
can see, 9-CURRENT is quite stable right now (and should be much faster 
than the 7.x you are proposing to use).
