I also have a CRT monitor where historically there was difficulty in getting
recognition of VGA with a g33 chipset.  I dealt with this issue three years
ago based on someone else's advice by inserting the following line in the
xorg.conf Device section.

Option          "Monitor-VGA-1" "Monitor_ID"

where "Monitor_ID" is the string used to identify the monitor.  That xorg.conf
has worked ever since, and I believe the above line is still required because
my X log file has the following information:

(II) intel(0): Output VGA disconnected
(II) intel(0): Output VGA-1 connected

Anyhow, if you have some version of VGA that is connected (e.g., VGA-1 for
my g33), the above Option lets you choose it rather than using the
disconnected VGA by default.  To learn more look up the Option
"Monitor-outputname" using "man xorg.conf".

Hope this idea helps.
