Anyone who beliefs cryogenics will save them will surely make the proper arrangements, and will certainly register themself as a non-donor in any opt-out system. This is a non-issue if your mind is made up; you can opt-out, by design.

Many cryonics solutions are head-only to save costs. So it's not mutually exclusive with organ donation.

(by the way, I'm pretty sure that's what inspired the live heads in jars in Futurama.)

One may register for cryonics, and still donate organs.

I'm not sure I need my heart, kidneys etc. for future reconstruction. Important information might be located in the gut, but I'm sure we can extract many organs without touching those neurons.

Even then, I may be willing to sacrifice my hope of resuscitation to save lives today. And that's if I even bother registering for cryonics —as tempting as it is.
