direct rendering issue on slackware

Its almost a week now that i'm trying to enable direct rendering on my machine.
I have a intel chipset 82815 and i've tried most of google's advices on enabling it but i still get :
root@hell:~# glxinfo | grep direct
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
OpenGL renderer string: Mesa GLX Indirect
stuff i tried:
-loading the glx and dri modules
-adding a section "dri" to xorg.conf (mode 0666)
-compiled drm kernel modules and used them
-changing the driver line of the graphic section in xorg.conf from "intel" (that was set up from xorgsetup ) to i810
-tried to change xorf.conf-vesa

i'm frustrated.anyone has any idea?
if you need my xorg.conf file let me know and i will post it.

Two things:

1. post your xorg.conf
2. Have you checked the xorg log to see what errors there may be regarding the card?
