1. XF86Config for Cirrus Logic 5434?

I just bought an Orchid Kelvin MPEG Vesa Local Bus accellerator board
today (VLB is hard to find, but Halted Specialties Company in Sunnyvale
has about a dozen left for $29.95!)

This board uses the Cirrus Logic CL-GD5434 chip.

I have no problem coming up in 640 by 480 mode using this entry in XF86Config:

    Mode "640x480"
        DotClock        25.175
        HTimings        640 664 760 800
        VTimings        480 491 493 525
    EndMode

This is the original entry as given in XF86Config.eg.  But when I try to
use any other mode, such as 800 by 600 or 1024 by 768, no matter what I
enter in the file the server gives me the error message "There is no Mode
800x600".

The one thing I know about the card is that it supports 75Hz vertical
refresh rate, and these resolutions:

640x480
800x600
1024x768
1280x1024

The manual says nothing about dot clocks or timings.

It seems that getting XF86Config right is a very frequently asked
question.  Perhaps someone should collect a web site with successful
config files for different cards and monitors, and write a faq about how
to get the file to be set up right.

Also, I looked, and at least on SlackWare there is no configxf86 program.
Where do I find it?

Regards,

Mike
