/dev/kmem and uboot can both read the cpu serial number. There was a thread on the topic a few months ago; my phone is cumbersome enough that I'll have to hunt it down later, sorry.

The wiki refers to Intel chips.

The OMAP3530 TRM mentions a 128 bit CONTROLCONTROL_DIE_ID register in
Section 1.5.2 "Device Identification".  I'm guessing that's a chip UID.
You probably have to write a small kernel module to read it (unless
anyone knows differently?).
