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.
