I tried the fblevel thing back then, something happens, but it just
gives the nice white-glowing-to-purple/black display.
Anyway, when I booted this morning (one can not suspend with
video=ofonly, the backlight stays on in suspend?) the fb seemed to work
again, except for X, that didn't work as before...
I went to the university, remembered that backlight would stay on so did
a remote `sudo radeontool light off` and hoped it worked.
When I got back home and rebooted to produce the dmesg log you
requested, everything worked again. So, I hope I'll never have it
again, if I do, you'll get that dmesg log :) Thanks a lot anyway!

Paul
