Default Still confused

I have been going back and forth over the past few months with other members, trying to figure out if the first stage bootloader of the HTC Flyer is signature checked by the on-chip boot ROM. I really want a device that is not at all locked down—forget unlocked bootloaders, I want an unlocked boot ROM. Does the boot ROM perform any signature checks on the the first stage bootloader? I want to hear an answer from someone who has done extensive experimentation with the tablets software.
I'm a crypto-maniac.
I may use words differently than you.
My terminology
signed: When any data, file, or message has a digital signature. Does not mean that something is checked for a digital signature.
boot ROM: Code physically etched on to a chip that loads modifiable code.
bootloader: Software that starts/loads the kernel. It is erasable.
locked bootloader: A bootloader that will only boot a kernel that has a valid digital signature.

You need to ask this question over in the development section, that is where the developers will see it.
