The issue: screen does not turn ON when resuming from suspend-to-ram. PC fans start working. I can even "gently" reboot the notebook, by pressing <Ctrl>+<Alt>+<F1>, then <Ctrl>+<Alt>+<Del>. But the screen does not work..
Note: resume worked with the Catalyst driver (but this blob has many other glitches...)
