Okay, we have a winner!
I just need to get the "okay" from Marvell,
and then I'll feed this patch for 2.6.29 and earlier -stable streams.

No need.  The earlier patch has no effect, other than speeding up your system
by a slight amount.  I'll submit that for upstream separately, along with a
fix for another "duh!" I noticed in the code.

In the meanwhile, you should keep the working patch (obviously)
in your kernels -- the same/similar patch will apply to earlier
kernels if needed.

Thanks to you and Brian for the legwork!
