how to enable DRI?

I have this weird problem. Direct Rendering keeps turning off, and i am quite sure, its not properly on, when it is.

at bootup i get Direct Rendering: Yes. GlxGears gives about ~11000fps, and is smooth. then i play bzflag, it is a little jittery, but within reason. I exit bzflag, and it doesnt exit, it just freezes. I have to do Ctrl-Alt-Bkspc, to restart X. I log back in, and lo-and-behold. Direct Rendering: No! Mesa GLX Indirect. glxgears is now jittery.
my card is an integrated intel X3100(GM965/GL960 chipset).
my laptop is an ACER Aspire 4920.

here is xorg.conf:
# Xorg configuration created by system-config-display

Can anyone shed some light on this?
