I'm easily convinced ;) Please let's get all the info into the right
place, make sure it answers the thus-far-asked questions (at least) and
we'll take it from there.

And please do have a think about switching as much as possible over to
runtime-configurability.  Because "please echo foo > /proc" is a heck
of a lot nicer than "please reboot with iomem=" which is a heck of a lot
nicer than "please ask vendor for a new kernel".
