I've further tracked down the if-clause. It has been introduced by Hui Yu, on
2002/07/11:

      - Fix Dell OEM VE card support
      - Add better clone mode support
      - Fix large panel (>= 1600x1200) detection and initialization problems
      - Remove "PanelSize" and "CrtScreen" options since they are no longer
        needed with new CloneMode and improved flat panel support
      - Add "DDCMode" option to detect and use DDC modes
      - Add "PanelOff" option to disable panel on laptops
      - Fix corrupted console problem
      - Other misc fixes
      (#A.1043, Hui Yu at ATI)

which is a huge 2279 lines patch, which basically introduces RMX and turns mode
selection upside down. Also, the infamous IsDell logic was introduced.

All in all I think this change is safe.
