Just for curiosity....

I own a samsung syncmaster 753DFX 17" CRT monitor, connected to a radeon
9200SE card.

In Windows, I can get 800x600 at 100Hz. But with x.org, despite of configuring
x.org properly, I can't get more than 800x600 at 85Hz...

Section "Monitor"
        Identifier      "SyncMaster"
        HorizSync       30-71
        VertRefresh     50-160
        Option          "DPMS"
EndSection

And vendor-provided .inf file says:

[sm783df.AddReg]
HKR,"MODES\1280,1024",Mode1,,"30-71,50-160,+,+"

So I don't really know what's going on and/or how I can make it work to 100 hz
in 800x600 mode and how windows can make it work, it the data is the same.

Writing a parser which extracts the relevant data from windows .inf files could help?
