Just for my own knowledge, I recall someone mentioning that the NCAA doesn't allow walkon/redshirts to get regular financial aid . . . is that correct??
it's not that simple. the rules are actually fairly complex. but for a simplified, mostly-correct, summary, the recruit can accept any aid for which he qualifies as long as that aid is also available to non-athletes. however, the recruit still counts against the sport's scholarship limit, regardless if he is on an athletic scholarship or some other form of aid.
there are some loopholes, though.
