I'm not sure if I have access to an mx31ads, but we have several i.MX
machines in our lab.  And I'm willing to give my comments to a general
cs89x0 cleanup.  (This drivers was one of the first things I saw when I
started kernel development.  Back then I gave up trying to understand
it. :-)  So maybe if you don't come around fixing it I might have some
energy to do it now with more knowledge about the kernel in general and
having seen *much* ugly code.
