solved the issue of having a good refresh rate right from startx. That is,
my special modeline was finally recognized, and the "PreferredMode" option
worked for the first time. So I am a happy camper after a couple of days
struggle with this. Thanks very much for your help and especially the
informed guess above!
Ok, now I'd like to find out why the driver uses VGA-1 on your board
instead of VGA. It's usually when there are 2 VGA outputs.
What kind of machine is this and what kind of monitor can you plug on
it?
Its an ASUS P5K-V MB with g33 chipset. See
http://www.asus.com/products.aspx?l1=3&l2=11&l3=542&l4=0&model=1652&modelmenu=1
for a description. There is some confusion about which GMA there is with
the g33. When I bought the card (a few days ago) the above site said it
used the gma X3000 and that agrees with what it says on the MB box, but now
the above site says its the gma 3100, and that is in agreement with
http://en.wikipedia.org/wiki/Intel_GMA and several other sites. I have also
found references that say the g33 chipset includes the GMA X3100!
lspci is not too helpful in getting this GMA confusion straightened out.

I assume all the "Unknown device" strings mean that this kind of hardware is
so new that it hasn't yet gotten into the authoritative PCI identification
data base (assuming such a database exists) or that it is there or Debian
testing does not yet have the relevant update. Is there something I could do
(I would need a cookbook because I have never fiddled with PCI
identification before) to get better identifications or do I just have to
wait?
The second and third entries from the lspci output above appear to be the
relevant ones. However, with this MB, there is only one video-relevant port
available at the back of the case which is an ordinary classical VGA port.
Currently I have
BusID "PCI:0:2:0"
in the Device section of xorg.conf and the log file says the following:
(II) Primary Device is: PCI 00:02:0
(WW) intel: No matching Device section for instance (BusID PCI:0:2:1) found
(--) Chipset G33 found
If I change the above BusID to PCI:0:2:1, X errors out (presumably because
PCI:0:2:1 is not connected with my monitor and cannot be because it is
somewhere on the MB rather than accessible at the back of the case).
My original report has (I believe) all the relevant log stuff, but if not, here
is the relevant EDID section for the monitor:
170 root 10 -5 0 0 0 S 0 0.0 0:00.00 khubd
172 root 10 -5 0 0 0 S 0 0.0 0:00.00 kseriod

This is a SONY 15-inch CRT monitor (Multiscan 15 sf II) I bought in 1996. At
the time it was considered to be one of the premier 15-inch monitors, and it
is still producing excellent Linux desktop results.
My own feeling is the type of monitor is not relevant to the current issue
of why
Option "Monitor-VGA-1" "Sony CPD-15SF2"
works and
Option "Monitor-VGA" "Sony CPD-15SF2"
does not. Instead it may be some error in the intel driver software
instead. Naively, you would think VGA would refer to PCI:0:2:0 and VGA-1
would refer to PCI:0:2:1, but all symptoms are consistent with those
identifications being reversed because I am using PCI:0:2:0 which apparently
corresponds to VGA-1 and PCI:0:2:1 is not physically accessible to me.
