disable_mclk_switching = true; gives 30fps and corruption (and eventually a gpu
stall)

disable_mclk_switching = true; and pi->mclk_dpm_key_disabled = 1; no
corruptions but speed is slow

with mclk_switching = true; and the patch disabling WREG32 setups, I get 30fps
& corruptions and gpu stalls/crashes

Ideas?
