The only authors that legally matter are the ones listed in the
copyright notices.  There are three copyright notices in the matroxfb
stuff: one is Petr, another is Gerd Knorr and the other is Matrox.  I'm
sure Petr has a pretty clear idea what he wrote, and I doubt Gerd would
get an attitude with you either over anything he did.  Since you haven't
even inquired about it, you don't have much to complain about as I see
it.

Or maybe the license incompatibility was simply a convenient way to cop
out of doing some work?

You can't copy and paste code.  You _can_ rewrite code.  Hardware
interfaces, trivial routines, and problems for which there exist only one
or a few obvious ways of solving them are all examples of where
copyright does not apply.  Porting any code from fbdev to a XFree86
driver *will* involve substantial rewriting.  I know this because I'm
currently doing it for the mga driver.

No.  The aim of open source licenses is to allow people to use the code
_under the terms the author chose_ without tracking down the author and
obtaining extra permissions.

I don't see how you have greater freedom with closed source licenses,
but feel free to elaborate.
