[Fixed] Writing IDE CDs with FreeBSD 4.7

I got a clue as to the nature of this problem because I got the
same error when attempting to use tar or dd onto /dev/fd0,
(the error was actually fd0 write_protected, which fd0 wasn't).

Some extensive googling eventually turned up a snippet that
suggested that setting a restrictive kernel security level could
cause 'operation not permitted' errors. Sure enough, I'm
(deliberately) running at security level 2.

I modified rc.conf and set the security level to -1 and right at
this moment I'm happily wiping a CD-RW with burncd.
