You can use SOURCE:
shell> mysql [plus any other options you need here]
mysql> SET FOREIGN_KEY_CHECK = 0;
mysql> SOURCE your_dump_file;
Or a cat trick:
shell> echo "SET FOREIGN_KEY_CHECK = 0;" | cat - your_dump_file | mysql
mysqldump will add the SET statement to its output in MySQL 4.1.1,
so this messing around won't be necessary.
