           Summary: VGA port fail to output video on RV370 system with git
                    driver of randr-1.2 branch
           Product: xorg
           Version: git
          Platform: All
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org

connect DFP & CRT monitor to DVI & VGA port of RV370, set video output mode to
1280x1024, VGA port fail to output video in this case.

It's because registers FP_HORZ_STRETCH & FP_VERT_STRETCH are not properly
initialized in the driver when VGA port is controlled by CRTC1.

I suggest initialize these two registers in the function
RADEONInitCrtcRegisters and set initial value by RADEONRestoreCrtcRegisters.
it's actually how the driver initialize them in master branch.
