Direct rendering does not work anymore in my system.

The report written above are the outputs got when setting "agp_size" "64".
With this setting I got direct rendering before.
Then, I tried to set "agp_size" "128" and the outputs were quite different:

Althoug with "agp_size" "128" it complains about agpgart, it is loaded
before startx and it remains loaded later. If I run glxgears with "agp_size"
"128" in xorg.conf, the window is black: no gears at all, and CPU is
working. This is from /var/log/kernel/errors when running glxgers with
"agp_size" "128":

If I try to run the game gl-117 with "agp_size" "128", the whole xwindows
becomes unusable and resetting X is not enugh to solve it: I have to reset
linux.
I have an ATI Rage Mobility-M AGP 2X (mach64 chip) with 8 MB in a Dell
Inspiron 3700. Mandrake 10.1 kernel 2.6.8.1-25mdk
Should I report this in bugzilla?
