OMAP3 uses e-fuse technology in the M-Shield security hardware, most likely to allow reprogramming of the public keys that are stored in the chip - a wise choice considering private keys can become compromised which would render the entire line of OMAP3 SoCs insecure.

I don't think the e-fuse technology is capable of crippling the OMAP3 hardware intentionally, however - seems like another hoax to me.
