Hypnotism is an obvious mind-affecting spell or power, and thus, would not work on risen dead, who are mindless. Undead ignore mind-affecting spells or powers as indicated in the d20 SRD.
I wouldn't expect it to work on things with 0 INT/WIS, but I see nothing in the Conan RPG about this...
Also, I wonder how Hypnotism works on Swarms?
