I'm experimenting with XFree86 4.3.0-0pre1v4 and I installed the
xlibmesa-drm-src package to get OpenGL working on my Radeon. There's one
problem though: dpkg complains loudly because the new DRM modules would
overwrite the old kernel modules, so either one rebuilds his kernel
without old DRM modules or he has to --force installation.
This patch solves the problem by diverting the old modules out of the
way, to a directory called /lib/modules/$(KVERS)_diversions. It works
for me, but it's really just a quick hack: for example, I preprocess the
preinst and postrm scripts with sed instead of m4 because I know nothing
about m4 and I couldn't get it to work. I hope the idea is fine though.
