I have a 19 inch Hitachi (HM-4119). It is 48 khz horizontal and 60-70
vertical, just for giggles.

Here is my "monitor" section of XF86Config...

Section "Monitor"

    Identifier  "Hitachi Monitor"
    VendorName  "Hitachi"
    ModelName   "HM-4119"

# Bandwidth is in MHz unless units are specified
    
    Bandwidth   100.0
    HorizSync   48-52
    VertRefresh 58-64  # typical for a single frequency fixed-sync monitor
    
    Mode "1056x796"
        DotClock        64.98
        HTimings        1056 1160 1272 1312
        VTimings        796 800 812 846
        Flags  "-vsync" "-hsync"
    EndMode

Section "Screen"
    Driver      "svga"
    Device      "Cirrus 5422"
    Monitor     "Hitachi Monitor"
    Subsection "Display"
        Depth       8
        Modes       "1056x796"
        ViewPort    0 0
        Virtual     1180 850
    EndSubsection
EndSection


Notice that the flags "-vsync" and "-hsync" are necessary with my
Hitachi to make the sync pulses go in the proper direction, which is 
negative-going with my monitor, whereas a garden-variety VGA is 
positive-going.

I also have to use an old 13 inch Mono monitor to see what is happening 
when the machine is booting. 

Why wouldn't it be possible to modify the console driver so that the scan 
rates could be changed on it to allow those of us with large, fixed-scan 
monitors to see boot messages and use the virtual consoles? I'm gonna go 
look to see where the video card is initialized.
