New log attached. However there is something bad going on. There are two bugs
affecting this game. This one and bug 60965, however when I reported them, this
bug used to disappeared with RADEON_DEBUG=noopt and bug 60965 didn't. Now when
I use RADEON_DEBUG=noopt, the corruption from bug 60965 is much worse and is
all over the place. The change did happened with 
f6c061261885fed0c83c437e9459ba79618f1b3a is the first bad commit

    st/mesa: convert ir_triop_lrp to TGSI_OPCODE_LRP

    AFAICT, all gallium drivers implement TGSI_OPCODE_LRP.
    Tested with softpipe, llvmpipe, svga drivers.

without RADEON_DEBUG=noopt the corruption is still the same, so my guess is
that r300 compiler somehow doesn't like TGSI_OPCODE_LRP, optimizes is away a
little bit, but not completely.
