If the future denizens are capable of restoring a cryogenically frozen person to life they shouldn't need our help with the DNA sequencing. After all, we can do that with fairly good reliability today on mummies and bog men so our Walt Disneys shouldn't be too hard to get a decent sample out of.

The epigenome, on the other hand, is a stickier issue; there's a lot of proteins vital to gene expression which are not going to fair well in either the initial freeze or long-term storage. Once we get reliable sequencing of that I'd say that sort of info would be much closer to what you're thinking of.
