Black screen at boot process

I've recently emerged the power management modules in kernel (powersave, performance governor...) and now everytime i turn on the pc, it shows until "Waiting for udev..." then a black screen and i can see the login manager (slim).

How to fix that?

If I had to guess, udev loads a KMS graphics driver module. If you have framebuffer console support built as module and not loaded, the screen will go dark, until X starts or the fbcon module is loaded.

I've added fbcon to the automatic loaded modues and it worked.

Thank you.
