I forgot to say that when I manage to get a non-composited LXDE desktop running on Radeon X1950 PRO, started by hand using `startx`, and I run the Unvanquished game, more than 51% of the CPU time is spent on OpenAL thread, i.e. the audio thread, which is wrong. This thread is usually really lightweight compared to other threads. Also, sound crackling is heard.
