Yes, ata is gnarly in places...

If a fix can be dropped straight into a 7.2 tree, then that is even 
better... I could try testing a NanoBSD image of HEAD on this machine if 
the change set delta between branches is sufficiently huge to prevent 
backporting the fix; this is my desktop machine and this is the only 
critical bug I've run into so far with 7.2.
