i have not tested olafs distro but it looks very good imho. but everybody who has problems to get it to run on a real hardware should give a pure nightly a try. the distro might be too heavy.
optionally i would try to boot aros68k without startup-sequence, soft reset after aros softkick (ctrl+amiga+amiga) and then both mouse keys pressed as ever. aros early boot will appear where as customary boot without s-s option can be chosen. now aros will boot to a shell. since black screen might be caused by wrong screenmode set, you can delete screenmode.prefs in envarc from the prompt and restart to see if that helps.
