I don't think anyone knows for 100% sure this year - last year you had it for the entire time as long as you checked in on the last day of the offer, but rumors (and they are just rumors at this point) are it won't be the same this year...
HOWEVER I have read that the Bounceback
free dining people for this year (2008 stays) (resort guests who were able to book it a year ahead when they stayed at a WDW resort last free dining period)
were allowed to still have it for their entire stay (one poster posted that they were checking in on the last day of that Bounceback free dining offer and have free dining until Oct 4 of this year), so it's hard to say if they got that because they booked last year, or WDW is going to allow the last day check in again for everyone.
Hopefully it will be extended again this year for everyone, but we'll have to wait for the "fine print" details when it's released I guess
