This happened to me on SunOS 4.1.[23] a few years ago. In my case (I lost a bunch of C files) it was a matter of reading the cylinder group with dd and searching with Perl. Since most files were under 8k, I found them contiguously. In SunOS, writes were organized in 8k blocks (more in some machines I think). If FreeBSD does the same then probably you have to do much less thinkering to assemble the files again.
