Adam --

this is exactly why SpamAssassin exposes its rule system.

        header MY_WHITELIST     X-My-Whitelist-Header =~ /yes/
        describe MY_WHITELIST   Contains my whitelist header
        score MY_WHITELIST      -100

Just cut and paste those lines into /etc/mail/spamassassin/mywhitelist.cf;
easy!  And you can use any header you like.

Patrick -- similar would apply for whitelisting on subject; use

        header MY_WHITELIST     Subject =~ /magictag/

(BTW this should probably be a FAQ ;)
