Just try a 3D app using textures or such like gl-117 from gl-117.sf.net
or torcs from torcs.sf.net, if you get framerates above 10 with these,
DRI works.

I've very similar HW and gears/glxgears have the same FPS with DRI enabled
and gears seems to be an very ancient demo which is not very useful to test
wether HW acceleration is used or not, todays CPU to the simlple flat view
used in gears.

Even if you make glxgears fullscreen, you will not see much difference
because your Celeron 2.0 GHz can render glxgears at the same Speed as
the R100 chip on your Mobility M6 LY. I've only got a 1.5 GHz Celeron
and see little difference with glxgears beween DRI and mesa software rendering.

I think XFree should add a a (generated) texture and maybe more to glxgears
to allow the Mobility DRI to perform with visible difference, maybe it should
refer to some other demo(e.g. from Mesa-demos), but I don't know them.

Maybe I've seen higher FPS with gears on XF4.2 (can check) so if this
is really the case, gears may be exploiting some performance degradiation
in some edge from 4.2 to 4.3, but I can tell that the games I tested
run faster with XF4.3.

Note that there are some bugs in the R100 support in the XF 4.3.0 tarballs
because the DRI Experts fixed some bugs after XF 4.3.0 was released. You
can see these problem if you use a display manager to login/logout (hard
lockup possible) and when you move/resize/clip complex 3D app windows like
gl-117, torcs or fireflies(X server lock, login over the network and kill
the app then). These bugs have been fixed in the mesa-4-0-4-branch of the
dri cvs(see CVS infos @ dri.sf.net for infos on the cvs branches)
