Half a year passed since my first email in this thread, and current kernels (4.0-tobe) still does not work properly. Meanwhile, I found this thread: http://www.linuxquestions.org/questions/slackware-installation-40/black-scre... which seems to help. I wonder where they got these boot params from...
Thanks,

Hello again.
It's been 4 more months since last message in this thread (which was mine). Now kernel 3.16 has been released, and I decided to give it a try. And it behaves just like all previous kernels, -- once gma500_gfx module is loaded, screen goes blank, monitor turns off ("no signal detected") and nothing to be seen until reboot.
Can we try to debug this somehow, after more than half a year?... :)
Current debugging (by 3.16), after:
modprobe drm debug=6 modprobe gma500_gfx
