Assuming the resolution of the display is configured correctly the
only thing I can think of is the x.org ati driver using the wrong
reference frequency, which it is know to not detect (correctly) on
sparc64 (actually with no BIOS for the graphics chip present). One
can set it manually by putting:
Option "reference_clock" "28.636 MHz"
into the respective 'Device' section of xorg.conf. A value used by
some other chips is 29.5 MHz.
If that doesn't make a difference you probably should try a newer
version of the driver by manually updating the port.
