Doubts dog anonymous Thinkpad code for Linux kernel

I thought this merited posting because it illustrates well the processes of open development in the Linux kernel. Contrary to SCO's claims, everything is documented and the various developers insist on it. There is nothing haphazard at all about the processes or the documentation.

As I understand it; the code in question is directly related to Lenovo's decision to ship at least one model of Thinkpad (the T60) with pre-installed Linux. The anonymous coder could be a Lenovo employee. Or not. The worry is that the code violates someone's intellectual property and, while the coder may well be allowed to remain anonymous, she/he will be forced to come clean to the kernel maintainers in order to assure one and all they are not infringing on someone else's claim.
