Red Hat GUI prob-- Video or Monitor?

I am in Red Hat Hell.  

Recently built a new PC out of a Jetway P4MFM motherboard
(www.j-mark.com -- not much help, and no email address),
2.0GHz Pentium 4, with 32MB onboard video.  Got a dual
boot Red Hat Linux 7.2/ Windows 2000 Advanced Server
running on it.  Under Windows,
[Control Panel/Display/Settings] is:
       Colors:        16 bit
       Screen Area:   1024x768
       Display:       Plug and Play Monitor on S3 Graphics ProSavage DDR

To run Windows, I ran the disk that came with the
motherboard to "install the VIA P4M266 VGA Driver."  
[Control Panel/Display/Settings/Advanced/Adapter] shows:
       Adapter Type:        S3 Graphics ProSavageDDR
       Adapter Information:
       Chip Type:           S3 ProSavage DDR
       DAC Type:            S3 SDAC
       Memory Size:         32MB
       Adapter String:      S3 Compatible Display Adapter
       BIOS Vers:           30.00.06

My monitor is a 5+ year old Micron 17Vx that came with
a now defunct PC.  I miraculously have the manual that
came with it, and it lists all its modes, of which here
are the relevant ones:
       Mode         HSync         VSync         Standard
       640x480      31.5KHz       60Hz          VGA
       640x480      37.5          65            VESA
       800x600      46.88         75            VESA
       1024x768     48.4          60            VESA
       1024x768     56.5          70            VESA
       1024x768     60            75            VESA
       1280x1024    64            60            VESA

Now.  I can't get X to run under Red Hat Linux 7.2 on
this machine.

Before installation, Red Hat asks for the *exact*
graphics board I have.There is no listing for "S3 ProSavage
DDR".  There are many "S3" listings,including: S3 Savage
(generic), Savage 3D 86C30, Savage 4 86C396, etc, etc.  
I of course select the generic.  It just takes it, and
then goes through the whole 20 minute installation.

After installation, it asks for Monitor Configuration.  
There is no listing for "Micron" at all, so I try
everything generic, or typing in at the bottom:
       Horizontal: 31.5-64.3KHz
         Vertical: 60-70Hz
After every settings attempt, when I press to the "Test
Settings" button, thescreen freezes, then briefly goes
blank (ie, it didn't like that setting).

I cannot believe that Microsoft can work out of the box,
but that it's impossible to run Linux.  

I don't know if it's the onboard video or the monitor
that's the problem, but it seems that if I can get a
Windows to work right out of the box, it _shouldn't_ be
such a stretch to get Linux working.  WHY is Linux such
an asshole about settingup the graphics configuration?  
Am I damned to using Linux only in text mode?  

Help me, Obi-Wan Kenobi...
