Brain injury kept Roy Walford from being cryopreserved, though there it was clearly an extension of his own thoughts on the matter: http://www.cryonet.org/cgi-bin/dsp.cgi?msg=24045 I see that as a terrible shame; it is guessing in advance as to the limits of what can be restored.
EDIT: I find it ironic - as he was my first exposure to the science of mind and thought etc... I find it ironic that his own death was due to a failure of the brain/mind in some way given how much he has contributed to the idea of thought and mind in his career.
I mean apart from the technical expertise on freezing etc, the rest is mostly wishful thinking about how such a facility will survive long enough in tact (and the US wont itself go the way of the Assyrian, the Persian, the Roman, the British and other empires, in 1 or 2 centuries time), technical/medical resurrection will be possible, and future people will care to resurrect those in there.
Even if a great current mind was preserved there, if people of the future are, say 2x brighter than us (not to mention having access to advanced AI) it would make little sense want to resurrect them for that alone. And as for having access to 20th-21st century info, with our trillions of bytes of video, images, texts and sound recorded every day, they'll likely want LESS, not more information about our times.
