Future Amendments Are Out of Order

The Senate health care bill contains provisions that purport to prevent a future Congress from revising portions of the legislation my majority vote.  Specifically, at pages 1019-1021, the bill requires a three-fifths vote in order to alter or repeal recommendations made by the Independent Medicare Advisory Board.  The relevant language is below.  As noted here, some Senators are upset by this provision.  My questions are 1) Is there much precedent for this sort of thing, specifically altering Senate rules in substantive legislation? and 2) Can the current Senate bind future Senates in this way?
