I see the promising software fix being worked on here:;a=commitdiff;h=1d04b142ffeaa15129f046751f1366b0f0614f47

and some test result...

So I installed the latest build with the patch and got nice results with the
values of these new glamo driver parameters as they came with the build.

So the hardware fix is looking like a waste to do.

The OpenMoko team is doing a great job and I am confident we will get their
recommendation is short time.
