I haven't seen any results that confirm this. Your results seem to show
that the xorg.conf change was bogus.
Moreover, the X server logs show that the shadow framebuffer was never
actually enabled for any mach64 test.
So it's an open question.

Actually, all of your fbdev tests use the shadow framebuffer, according to
the X server logs. As Michel said, that's the default for fbdev. That's
all good. The shadowfb test is only relevant as a workaround for the
mach64 bug.
Anyway, the point I was trying to make here was simply that Xfce issues
aren't necessarily X server issues (though they may be).
