It seems pretty clear that the problem is that arandr, gnome-display-
properties et. al. are requesting display sizes that are bigger than the
maximum texture size that can be supported by the i945gme chipset. The
problem really needs to be fixed in at least two places though, the
tools shouldn't request sizes that are bigger than the maximum texture
size compiz will be able to obtain, compiz should be guarded to make
sure it doesn't request oversize textures and fallback gracefully and
the driver shouldn't lock hard if it is requested to provide a texture
size bigger than it supports. Defence is depth is required otherwise
this can be used to DOS a machine even if the userland tools are fixed
up.
