           Summary: radeon driver fails for RS482 [Xpress 200], did work
                    with Xorg-6.9
           Product: xorg
           Version: 7.3
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: peb at mppmu.mpg.de
         QAContact: xorg-team at lists.x.org


With new hardware we had to switch from Xorg-6.9 to Xorg-7.3 (or the upcoming
7.4). This works mostly fine (e.g., we can use the nv driver instead of the
proprietary nvidia one).

But we have serious problems with the RS482 [Radeon Xpress 200] on some of our
systems (reading the ChangeLog that seems to be a problem child):
  PCI: 01:05:0: chip 1002,5974 card 103c,280a rev 00 class 03,00,00 hdr 80

Everything looks fine, except that the screen is white (but does accept
keyboard input).

That card used to work just fine with Xorg-6.9, and if the problem cannot be
fixed, we may have to keep this old version around just for these few systems.
