VBO and other opengl stuff is broken on some old low-end arm5/arm6
phones (mostly 1.5, 1.6), due buggy opengl drivers from gpu vendors.
Some phones got update to 2.1/2.2 and now do not have this problem.
Anyway LW not supported on phones with 1.5/1.6 Android OS.
Btw. not all phones with 2.1/2.2 support LW (due memory limitation or
just for no reason).
