Maybe distros were slow or errant > in picking up the patch. It went into 2.6.25.8, which was the stable line at the time. It didn't get backported to 2.6.24. Ubuntu's stable line is called 2.6.24-19.41, and I'm guessing they just didn't realise it was a fix that actually needs to be applied to everything back to at least 2.6.23. I'll go try launchpad again and see if it's unbroken enough to accept my bug report.
