Yep, I blew it

The 41% number was wrong; the article has been edited with the correct data.
For the curious: the bug was a combination of the tool descending into the .git directory (which has no history of its own) and it attributing unknown lines to the oldest release. That essentially inflated the number of "old" lines in the full kernel by about 2 million - enough to make a big difference.
Please accept my apologies for the screwup. I'd taught the program to avoid .git a while back, but I thought it was an efficiency improvement only; I didn't realize it had messed up the full-kernel numbers. Embarrassing.
