Thanks for your explanations. Recently tried it. But...:

with
> linux   /boot/<blah blah blah> radeon.aspm=0 radeon.dpm=1
still blank screen after starting kernel loading

with
> linux   /boot/<blah blah blah> radeon.modeset=0 1
it seems it's booting but I can't see command line - only black screen or text
line: "kernel booting... bla-bla-bla" and also no command line. Trying to enter
anything gives nothing. But if a enter "reboot" and press Enter it restarts. So
it gets the commands but I can't see any display output.
