--- Comment #11 from Peter energonic@gmail.com 2013-05-21 10:15:05 --- Still on iMac, installed fedora 18 on partition previously used by Arch (would boot using KMS into black vts). fedora using kernel 3.6. Behaved like Arch did previously; had to use kernel option 'nomodeset' to get any vt screens and that stopped radeon module from being loaded by X (Xorg.0.log had: '[KMS] drm report modesetting isn't supported' and this was followed by 'No screens found')
Now upgraded fedora to use kernel 3.9.2 and, as with Arch, get black vts even if 'nomodeset' on kernel boot line.
The current kernel 3.9.2 is of no use on my system; I have no way to boot it and run vt screens. Others who might need nomodeset may also be affected.
