Configuration de X, NVidia RIVA TNT2



bonjour,

j'ai une carte graphique NVidia :
"Chipset RIVA TNT2 Model 64/Model 64 Pro" (/var/log/XFree86.0.log...)
je tourne sous woody, 
avec les paquets nvidia installés de manière conventionnelle
(apt-get install + README...)

globalement, ça tourne, 
mais !
  * le démarrage du serveur X est très lent : 20-25 secondes entre 
startx et l'appartion du splash-screen de gnome (BOF)
j'ai l'impression (visuelle) que l'écran (LCD : iiyama ???)
passe en revue pas mal de modes d'affichages !?

  * le passage mode graphique/texte est lent aussi (qq secondes)
(ce point là est peut-être normal)

  * cat /proc/nv/card0 renvoie :
----- Driver Info ----- 
NVRM Version: NVIDIA NVdriver Kernel Module  1.0.2314  Fri Nov 30 19:33:20 PST 2001
Compiled with: gcc version 2.95.4 (Debian prerelease)
------ Card Info ------
Model:        RIVA TNT2 Model 64/Model 64 Pro
IRQ:          10
Video BIOS:   02.05.11.00
------ AGP Info -------
AGP status:   Enabled
AGP Driver:   AGPGART
Bridge:       Via Apollo Pro KT133
SBA:          Supported [disabled]    <- si c "supported", j'aimerais que ça soit "enabled" !
FW:           Unsupported [disabled]
Rates:        4x 2x 1x  [4x]
Registers:    0x1f000207:0x00000104

or, si j'ai le malheur de rajouter la ligne
"options NVdriver NVreg_EnableAGPSBA=1"
dans /etc/modules.conf,
je suis bon pour un hard-reset dès que je lance X :-(

d'un autre côté, je ne c pas trop ce que c ce "SBA",
ni si cela m'apportera koi que ce soit !

voila pour mon désarroi...
damien

voila aussi mon XFree86Config-4 :
