I've done that now. The 'auto' search didn't work, but I was able
to find in the database all the working drivers for a T20. The S3
Savage card works with the 'savagefb' driver.
However, I'll leave this for the time being as I now have a fully
working install of Etch with Kde.
Just to make sure that you will not waste time later on: The savagefb
driver is a framebuffer driver which has nothing to do with X. It can be
used instead of the generic vesafb for the tty (non-X console) displays.
You probably have already seen Chris Bannister's recent post in this
thread; try the "s3" and the "s3virge" driver that he suggests in your
xorg.conf. (You need the packages xserver-xorg-video-s3 and
xserver-xorg-video-s3virge to have them available. Maybe these packages
were missing in your first install and that caused the problem with X.)
