There are a whole slew of later changesets that haven't made it in yet. The root cause of your particular problem is not the lun copy optimization, but a problem with the layout of a data structure that is dma'ed to the controller and a controller errata. The fix for this is available in the 20030603 bksend file at my site:

I will try to find some time later this week to review the code that is now in 2.6 and generate updated changesets for that branch.
