I've updated this OP to make it easier for new comers to find some of the most important posts as well as a few important outside links that inform this thread. It is my personal feeling that if you are reading these forums, and considering buying ANY Android phone, this thread is a very important one to read. It is far better to be informed than to realize after you buy a product that it wasn't what you expected (I almost made this mistake).
The main purpose of this thread is to discuss what a signed (encrypted) boot loader is, what the implications of having a signed boot loader are, whether or not the Droid X may have one, why you may care, what you may be able to do about it if you do care, etc, etc.
This thread is filled with a lot of long posts (including this one), so prepare yourself for that. Not all of them have tons of merit (mine included) so keep that in mind.
Below are some of the most informative posts you'll find in this thread. That said, I highly suggest further reading: there are many great ones that I haven't linked to here.
EDIT (7/8/10): This thread was just opened and indicates that our fears may be correct and the boot loader is signed. http://androidforums.com/motorola-d...-may-rooted-but-has-encrypted-bootloader.html
EDIT (7/10/10): This is a highly technical post (at least in my mind) in which a user describes methods he thinks may work to get around an encrypted boot loader. If you really know your stuff too, please take a look at it and consider posting your thoughts on his suggestions.

EDIT (7/13/10): Turns out the DX may have even stiffer security measures than we originally thought. For more details see the two links below (the second one is extremely scary stuff):
> The DroidX: Security and Discovery Steven Bird
> How the Droid X is locked down? Let me tell you what I know.
(Links found in a thread over at XDA dev forums)
EDIT (7/15/10): the 4 links in this update are embedded in the text
> the good --> Steven Bird has turned his tone to optimistic: he is tweeting, blogging on his webpage and posting in a DroidXForms thread.
> the [really] bad --> p3droid, a well know hacker/developer and Aixelsyd, a well known leaker of reliable Droid X and Droid 2 info @ Howard Forums have some devastating posts in a different thread at DroidXForums. (WARNING: This will ruin the buzz you got going off the good news BIG TIME)
1) Good posts illustrating what it means to have root access and what it means to have access to the boot loader:

2) There is a difference between locking and encrypting (signing) the bootloader: it's encrypting that people are worried about.

3) If the boot loader is encrypted, there is an almost nonexistent chance that it will be cracked. (2nd link is methods that would be used to try to crack it)
