The example you give above *is* the correct syntax for having stderr of
'cpio' redirected to /tmp/test (instead of to the tty as is the normal case.)

The shell reads and takes care of all the redirection stuff before starting
the program.  In the example above 'cpio' will not see the 
"< /dev/ad0h 2>/tmp/test" part of the commandline, since the shell will not
pass it along to the program.
