Assuming it doesn't work with updated software, can you also try:

1) starting from a non-corrupted state, start nouveau with
nv_bios.c:call_lvds_script patched out:

--- a/src/nv_bios.c
+++ b/src/nv_bios.c
@@ -2965,6 +2965,7 @@ void call_lvds_script(ScrnInfoPtr pScrn, struct dcb_entry
*dcbent, int head, enu
        uint32_t sel_clk_binding;
        static int last_invoc = 0;

+       return;
        if (last_invoc == (script << 1 | head) || !lvds_ver)
                return;

and check whether the picture in X is ok, and whether the picture on returning
to console is ok.

2) Make register dumps while in X, and attach them here -- one with randr12
disabled (and no corruption present), and one with randr12 enabled and the
corruption present -- as follows:

git clone git://people.freedesktop.org/~stuart/radeontool
make
./radeontool regs > logfile
