That probably means that it's not owned by user root and group wheel;
unfortunately, the drag-install process doesn't cause the startup item to be
given the right ownership. (The dmg is probably mounted with the "make it look
as if everything on the file system is owned by the person who mounted it"
option, and the Finder's copy preserves the ownership.)
You'd need to open up Terminal and do
sudo chown -R root:wheel /Library/StartupItems/ChmodBPF

You need to open up Terminal and run it as
sudo SystemStarter ChmodBPF start

There are folders, and there are directories.
"Folders" are what the OS X GUI shows you. "Directories" are what are in the
file system name space; a "folder" is a directory that the GUI's willing and
able to display.
For better or worse, "/dev" is a directory but not a folder; the GUI hides it
from you. If you open up Terminal, you can see that it exists (if it didn't
exist, then
1) a huge amount of code in OS X would fail
and
2) Apple couldn't use the word "UNIX" in connection with OS X):
$ ls /dev
auditpipe ptyta ttyr6
autofs ptytb ttyr7
autofs_control ptytc ttyr8
autofs_nowait ptytd ttyr9
bpf0 ptyte ttyra
bpf1 ptytf ttyrb
bpf2 ptyu0 ttyrc
bpf3 ptyu1 ttyrd
...
