Fedora Core 5 S3/S3Virge videocard support problems.

[Crazy AMD K7]

Hello all Fedora Core 5 and Xorg users and developers.
I have upgraded to Fedora Core 5 and there are problems with S3
videocards. I have two questions.

1. How to make s3 trio 64(86C764X)videocard to work?

2. As I have read "man s3virge" it is supported.
How to make s3virge /DX(86C375) to work?
