What version of FreeBSD are you using.  On a 4-day-old 4.0-CURRENT,
fstat(2) seems to fill st_bklsize correctly.  The following sample code
prints 8192 for every file I tested on my system.

Ciao,
Sheldon.

#include <sys/types.h>
#include <sys/stat.h>
#include <err.h>
#include <fcntl.h>
#include <stdio.h>

int
main(int argc, char *argv[])
{
	struct stat t;
	int fd;

	if (argc != 2) {
		(void)fprintf(stderr, "a single path argument is required\n");
		return 1;
	}
	if ((fd = open(argv[0], O_RDONLY)) == -1)
		err(1, NULL);
	if (fstat(fd, &t) == -1)
		err(1, NULL);

	printf("%d\n", t.st_blksize);

	return 0;
}
