what excatly are you trying to do?  use just the vga port?  clone crt and lcd?
Can you post your full log somewhere?  You may have to use the
monitorlayout option if the second head is not being detected. also if
the port in question in the vga port on a laptop, setting the hsync
and vrefresh for the monitor will only affect the lcd screen.  if you
want to clone your LCD on your monitor either use the clone hsync and
vrefresh options or if you are using xorg from cvs, the crt2hsync and
crt2vrefresh options.
