I guess you know that the -mm kernels get everybody's not for
primetime code added to it, so the BUG() you got could have come from
anywhere.

If your comfortable with the process, I would start with 2.6.17-rc6
then get the #upstream patch(upgrade) from libata and compile up a new
kernel.  (Think thousands of lines of modified code.)

If you get any issues with it the lkml-ide devs will jump right on it I suspect.
