Failure to re-establish 3D video acceleration

Following a reinstall of debian amd64 lenny I am unable to get 3D acceleration (which was working fine before), although all checks are positive:

francesco@tya64:~$ glxinfo
name of display: :0.0
display: :0 screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
server glx extensions:
GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_SGIX_fbconfig,
GLX_SGIX_pbuffer, GLX_SGI_video_sync, GLX_SGI_swap_control,
GLX_EXT_texture_from_pixmap, GLX_ARB_multisample, GLX_NV_float_buffer,
client glx vendor string: NVIDIA Corporation
client glx version string: 1.4
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce 6600/PCI/SSE2
OpenGL version string: 2.1.2 NVIDIA 173.14.09

francesco@tya64:~$ grep Driver /etc/X11/xorg.conf 2>&1 |grep nvidia
Driver "nvidia"

tya64:/home/francesco# adduser francesco video
The user `francesco' is already a member of `video'.

$ glxgears

it is as slow as on another machine i386 lenny without nvidia driver and without acceleration. This confirms that 3D is not working.

Adding the line

option "ForcePCIMode" "True"

to /etc/X11/xorg.conf (section Device)
did not help, and was therefore removed.

Thanks for help

I posted also on debian forums. Nothing useful came out.

Your glxinfo output shows that direct rendering is, in fact working. glxgears is not a benchmark and should never, ever, ever be used to determine if 3D acceleration is working. Have you tried other applications such as openarena?
