           Summary: additional VGA card must be present (but not used in
                    xorg.conf) for radeon to work with EXA
           Product: xorg
           Version: 7.4
          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: phercek at gmail.com
         QAContact: xorg-team at lists.x.org


When I pull out second (unused) vga card (RV100 PCI) the first one (RV670Pro
AGP) stops to work with EXA enabled. The image is corrupted (top 2 thirds of
screens are black and the bottom third contains horizontal black and white
stripes. Well, this is how it was with radeonhd 1.2.5. Radeon driver at that
time did not work at all. Today, I tried git versions of radeonhd and radeon
too. They behave identically now. When both VGA cards are in and only the AGP
one is used it works correctly. When I pull out the PCI card I do not get any
image, screens are black. Only mouse cursor is correctly rendered.

Version information:
vga cards have stock bios
libgl 7.4.2-1
mesa 7.4.2-1
drm - git version
  _gitroot="git://git.freedesktop.org/git/mesa/drm"

ati - git version

I'll attach the log file and xorg.conf.
