s3 savage4 help needed

Hello,
I post this message also to dri users mailing list.
However I post also to this group because I don't found a solution and
the web seems
to lack of references about it.
I have some trouble trying to make dri works with my card (glxgears
hangs or black window
appears, so I think the problem is with 3D). It is a S3 savage 4 card
with 16384 k video memory.
Suggestions about what to do (recompile, re-configure anything) could
be useful..
I include logs here (I follow dri.freedesktop.org steps on
troubleshooting):

xdriinfo
Screen 0: savage

glxinfo | grep "direct rendering"
direct rendering: Yes

lsmod lists these modules : savage, drm, via_agp, agpart, i2c_savage4,
i2c_algo_bit, i2c_viapro, i2c_core

All these with:

- Slackware 11.0, kernel 2.6.17.13, X.org 6.9.0, savage_dri.so driver
downloaded from snapshots (savage-20060403-linux.i386.tar.bz2),
OpenGL renderer string: Mesa DRI Savage4 20050829 AGP 1x x86/MMX/SSE

the computer hangs with glxgears after a little movement of mechanics.

I tried also with:
- Foresight 1.0, kernel 2.6.19.2, X.org 7.1.1

glxinfo complains : "libGL warning: 3D driver claims to not support
visual 0x4B", so does glxgears but then hangs.
and:

- Zenwalk, kernel 2.6.18.6, X.org 7.1.1

launching glxgears appears a black window (but no hangs).

Bye,
Gaetano
