That should capture all the background on the various instances of this bug that I've been working with people on. Basically, there are some variations in symptoms but all of the reports are particular to Arrandale, occur in relationship with setting up external screens (perhaps something relating to primary monitor settings), and appear to be fixed in the latest kernel.
The next step for this bug is that we need to narrow down what patch in the upstream kernel provides the fix. The best way to achieve this is via doing a git bisection search. Unfortunately none of us Ubuntu-X guys have Arrandale hardware, so if this bug is going to get fixed in natty we need a volunteer to do this. It is a bit technical but well documented in a paint-by-numbers fashion at https:/
