I added this to my tree with Tomas's title&changelog (thanks - I was
about to whine about that).  Thanks Thomas for the reminder.  I tagged
it as backportable to 2.6.25.x, 2.6.26.x and 2.6.27.x.


This bugfix has been there for a month and this driver has been busted
since 2.6.24.  Is anyone out there?  Mark?  James?
