Opening /sd0@ for reading should work.  Tim Lindner's latest version of
SDIR uses the following code to open the device:

sdcPathName
    fcc    ./sd0 at .
    fcb    C$CR

* open path to driver
* uses A, X
open_path_to_driver
    leax   sdcPathName,pc
    lda    READ.+PREAD.     open for reading
    os9    I$Open
    lbcs   noDriverError    Fail if not opened
    sta    pathnumber,u
    rts
