radeon.modeset=0?

How come this is the only distro I have to do this? Is it because the kernel/Xorg ver. is too recent or what?
I can log the same laptop into Debian Wheezy and Mepis, no problem. Plus, Mint KDE.
I still get the 'screen haywire flicker' but at least, it moves on in the boot up.
I just thought there's still a ton of laptops with this hardware and the Radeon card only allows open drivers so I'm not sure why the 'code' is not included already?
Thanks for the info, though.
As for booting up in 'safe graphics mode', I find that rarely helps and that is my experience for several years regardless of the graphics hardware or distro.
