Yup, this is the right place.
Note, however, that the information contained in this email summarizes
my own interpretation of Sun and Blackdown access rules to the Java VM
source tree and should not be considered legal advice, nor be viewed as
official answers from Blackdown, my employer, or myself.

Just our of curiosity, what's that CPU?

Here's how it works: Blackdown has its own CVS where sources are stored.
In order to get access to that CVS you need to 1) Contact the CVS
maintainers 2) Have them provide you the contract, which is really
between you and Sun Microsystems
As far as I know, I was the last person who was fortunate enough to get
access to the Blackdown repository. That was back in 2002 I believe.
Looking at emails at got recently, things are getting much more
complicated.
Moreover, the Sun Community License is already restricted enough. You
can't really use it for a product you'll distribute.

Not that I know of. The contract between Blackdown developpers and Sun
Microsystems allows us to distribute patches, but we need to be *really*
careful not to provide too much stuff in the patch. That might explain
why you won't find any Blackdown patch on the Internet. I know I
wouldn't take the risk to distribute one :)
On the other hand, the way I understand it, the source tree you'll get
access to from Sun is way different from the one we use for the
Blackdown project. So a Blackdown patch might now apply cleanly on the
Sun source tree. Not sure about it though, as I have never downloaded
sources directly from sun.

See previous answer.

No idea. I don't have control over the cvs and/or the registration
process. Karl Asha does. In my opinion doing this will be difficult.
