VGA resume & thaw (wake up from S3 & S4) broken - kernel exclusively
Actually I have nothing to show cause logs are all OK.
Haha, it seems to me that the bugs become intelligent.

Logs(dmesg) are literally identical.
3.15.10-201.fc20.x86_64 - nouveau(fb) resume & thaw PASSED, and that's all what
works.
Kernels >= 3.16 - nouveau(fb) resume & thaw BROKEN
ALL Kernels - vesa(fb) resume & thaw BROKEN.
Have a nice weekend folks.
