Compiled it (hope that -glx and -dri packages are enough to install) and here
are my impressions.
Lightsmark works 90% okay. Still there remains some minor issues with texturing
(first scene - some texturing artifacts on the window). As a bonus -
reflections now partially works too (not reflecting correctly though) so i
guess we are on the right way to fix this issue. Im not at home right now so i
cant test much more.
