kakra at jupiter ~ $ dmesg|fgrep -i "rc6"
[    0.000000] Kernel command line: quiet real_root=/dev/sda3 
real_rootflags=compress=lzo,subvol=root64 fastboot zcache

[    1.000514] [drm] i915: Enabling RC6

This seems to work...

Did not try the others but I suppose my system hangs with deep rc6. I will 
test this a few days.
