Forgot to say: you probably need r300_dri.so and radeon kernel module
debug symbols to get more detail.
At least I very much hope that the radeon_dvi_detect isn't correct,
because otherwise it would mean that the kernel module spends more
time probing the DVI port than MPlayer uses for all of decoding
and (de)noising together.
