Yeah, well, the RHEL stuff I assume is released; their own heavy enhancements, I don't know.
It doesn't matter if someone else released source. Anyone distributing binaries containing GPL code is supposed to also supply the matching source along with anything else that becomes part of a derived work.
IIRC, I don't *think* that if you take it and enhance it, you're required to release your commercial enhancements. For example, video drivers, proprietary.
The whole point of the GPL is to require the release of source (to anyone who gets binaries) of any derived work. Kernel modules aren't strictly considered to be derived from the kernel, although there has been some speculation that they could be.
