Mike -

It's obvious to me that I'm going to have to test this monitor
extensively over the next year on your behalf.  Contact me off list for
contact information and I will meet you in a darkened, secluded
location. :-)

Seriously, though - schweet monitor.  I'm not sure that you specifically
need modelines.  Modelines are but one way to describe modes. 
Alternatively, you can define modes the way Mandrake's XFdrake makes
them at install time.  Below is a cut-down version of my
/etc/XF86Config-4:



Section "Monitor"
    Identifier "monitor1"
    VendorName "Unknown"
    ModelName  "Unknown"


# HorizSync is in kHz unless units are specified.
# HorizSync may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.
    HorizSync  30-85


# VertRefresh is in Hz unless units are specified.
# VertRefresh may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.
    VertRefresh 50-160


# This is a set of extended mode timings typically used for laptop,
# TV fullscreen mode or DVD fullscreen output.
# These are available along with standard mode timings.

If you plug in the HorizSync and VertRefresh ranges from the spec and
pick a DefaultColorDepth from your vid card specs (let's assume 24 bits
is good), then you can have the following:

    Subsection "Display"
        Depth       24
        Modes       "1600x1000"
        ViewPort    0 0
    EndSubsection

and see if you get anywhere.  Personally, I'd like to see if I could
fire up that 1920 × 1200 mode.
