I fear this is the wrong direction to fix it. `auto-revert-handler' shall
not know about major modes. All what a buffer has to say to
`auto-revert-handler' must be in `buffer-stale-function', which is set to
`dired-buffer-stale-p' here.

What happens, if you remove the test for `buffer-read-only' from that
function?

Best regards, Michael.
