Never tested, but right now you can still post contents and headers, though it's a ugly hack. It consists in appending the headers and data after the HTTP version :

        option httpchk POST /something HTTP/1.0\r\nContent-length:\ 7\r\n\r\nfoo=bar

I told you it was ugly :-)

You may also have to specify a Host: header depending on your service, and maybe even a content-type. Find about it by trial and error. Please post your findings on the list, as I'm sure other people might be interested too.
