Dear Charles,

Just for the record: I'm always willing to help out as such.
One of the problems with pursuing these actions is that it can be somewhat hard to prove that you have contributed materially to claim copyright over some code.
There are some places where this is clear (eg. much of Wolfgang's u-boot work) or in my case Yaffs (where I have written all the core yaffs code).
In much of open source though, there have been many major contributors and even more minor contributors and it can be hard to claim to be a legitimate copyright holder. In theory, I guess you could claim copyright on a three line patch, but the harsh reality of lawyer land would probably want to see something far more substantial.
