Just to make this clear: I do not intend to port every single fbdev
driver to DRM. :)

I did, however, began to convert that Matrox driver. First, to see if
the approach does work in general; and because matroxfb is one of the
more complex drivers. If it can be converted, any other driver should be
convertible as well. I split up the driver code by HW generation and can
now refactor each generation on its own. I expect to end up with several
duplicated functions, which can be re-merged.

Maybe our repo can be helpful. Thanks for the link.

Best regards
Thomas
