we seem to have equivalent code already.  from i810_driver.c:

   /* Setting the OVRACT Register for video overlay */
   {
       CARD32 LCD_TV_Control = INREG(LCD_TV_C);
       CARD32 TV_HTotal = INREG(LCD_TV_HTOTAL);
       CARD32 ActiveStart, ActiveEnd;

       if((LCD_TV_Control & LCD_TV_ENABLE)
          && !(LCD_TV_Control & LCD_TV_VGAMOD)
           && TV_HTotal) {
           ActiveStart = ((TV_HTotal >> 16) & 0xfff) - 31;
           ActiveEnd = (TV_HTotal & 0x3ff) - 31;
       } else {
           ActiveStart = i810Reg->OverlayActiveStart;
           ActiveEnd = i810Reg->OverlayActiveEnd;
       }
       OUTREG(LCD_TV_OVRACT,
              (ActiveEnd << 16) | ActiveStart);
   }

which looks like a generalized version of what's described in the URL.

has anyone actually tested this?
