Having fglrx installed replaces the open-source libGL with ATI's libGL,
so you can't have both at once.

$ dpkg -S /usr/lib/libGL.so*
libgl1-mesa-dev: /usr/lib/libGL.so
libgl1-mesa-glx: /usr/lib/libGL.so.1
diversion by xorg-driver-fglrx from: /usr/lib/libGL.so.1.2
diversion by xorg-driver-fglrx to: /usr/lib/fglrx/libGL.so.1.2.xlibmesa
xorg-driver-fglrx, libgl1-mesa-glx: /usr/lib/libGL.so.1.2

 Removing fglrx removes the diversions, putting the mesa version back.

 I see you already fixed your "i810" -> "intel" problem.

 I've retitled this bug to what it's really about, and removed the hw-
specific and regression tags.  This package has always worked this way,
by moving aside the mesa libGL.  The NVidia binary drivers work the same
way.  And it's a "dll hell" problem, not a hw-specific problem at all.

 This could either be marked as invalid, or left around forever to mark
this as a known issue.  Unless /usr/lib/libGL is replaced with a wrapper
library that can use whatever's available, I don't see how this could
ever be solved.  I think it does belong assigned to fglrx-installer,
because it's replacing libGL with a libGL that doesn't support mesa
anymore.

 That sucks that a system with heterogeneous GPUs, some of which use
non-mesa drivers, can't do 3D on all heads without a chroot or ld.so
tricks/env vars.
