I gathered from the follow-up article to the one posted (sorry too
lazy to get the link, it's at the end of the second page), that it
must be possible to disable at least the most performance significant
bug "fixes", because he compares the same kernel with and without
them enabled. No idea whether that's set at compile time or is a
run-time option.
