Then it was possible if you took apart the tablet and soldered on a hardware modification. Now it appears that the Nook Tablet will be able to run unsigned kernels without requiring a hardware mod. This will allow the Nook Tablet to run custom ROMs including the popular CyanogenMod ROM.
Apparently this is not a flaw in Texas Instruments' M-Shield security hardware on the processor, but rather a flaw in B&N's use (or lack of use) of it. As is fairly common, the implementation of the security scheme fell short of the theoretical and expected security that the hardware could provide.
