Michel already answered your questions and I agree with him. One thing
to look for is libGL: make sure that the correct libGL.so.1.2 is
installed in the correct place, which is /usr/X11R6/lib on Debian and on
Ubuntu hoary, but was moved to /usr/lib for Ubuntu breezy and later (my
packages don't support that yet).

Using LIBGL_DEBUG=verbose should tell you what's wrong, but on my system
at least I see a message that I can't explain:

$ LIBGL_DEBUG=verbose fglrxinfo
libGL: XF86DRIGetClientDriverName: 8.19.10 atiogl_a (screen 0)
libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/atiogl_a_dri.so
fglrx: libGL version does not match - OpenGL module is using glapi fallback
libGL: XF86DRIGetClientDriverName: 8.19.10 atiogl_a (screen 0)
drmOpenByBusid: busid is PCI:3:0:0
drmOpenDevice: minor is 0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 4, (OK)
drmOpenByBusid: drmOpenMinor returns 4
drmOpenByBusid: drmGetBusid reports PCI:3:0:0
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9200SE DDR Generic
OpenGL version string: 1.3.1017 (X4.3.0-8.19.10)

The message that troubles me is the "using glapi fallback" stuff, but as
you can see 3D acceleration is working fine so it's not a fatal error.
