I would be willing to test a patch, however any fix would need to be back-ported
to the 3.2.0 kernel to be useful to me.  For the sake of testing though, I would
be willing to update to a newer kernel.

Also, I should warn you that I am not a Linux expert.  Thus, operations like
updating/recompiling the kernel are new to me and I'll need some help working
through the process.
