I believe the X radeon driver relies on parsing some information out of the BIOS. Since the Mac version doesn't have a BIOS in the format the driver expects, it does not work. There was only the one model of card and so no one was ever interested in fixing it. You can get X with the xf86-video-scfb driver, but it will be unaccelerated. -Nathan On 03/02/16 18:22, Jason Bacon wrote: > > If you can find out what it's most similar to that *is* supported by > Xorg, there's a chance it will prove very easy to add support for it. > > There is support for the X1900 series: > http://www.x.org/archive/X11R7.6/doc/man/man4/radeon.4.xhtml > > It *could* prove to be as easy as tweaking the radeon driver to > recognize the chipset as one if its supported models.
