OK...  this is all telling me that I *really* need to scrub this in
detail.  It's all sounding very vague, it's an area which seems to cause
lots of problems and I don't want to be sitting here next time around
trying to figure out if another rewrite makes things better or worse or
if another driver should look similar or different.

You know exactly what I mean - the early patches are in drivers/video,
don't touch anything outside of that and have no obvious dependencies.

But I thought everyone was saying this hardware doesn't work anyway and
that you want to apply all these changes to fbdev?

This means we're all then stuck reading reposts of the same enormous
series over and over again - as a reviewer a really big series that
appears from the subject lines to be mostly about another system is
really offputting.  If you're going to do something like this please at
least reply to the messages, that way it's clearer that there's not
going to be a dependency problem getting the patches applied (which is
part of what makes things offputting).
