will give a list assuming you use modules, I think all of them need =<num>.
Yep, that is one way of getting that info, thanks. I always go and look at Documentation/kernel-parameters.txt and forget about modinfo.
As you say 'radeon' needs to be module but since this is the case with the distros, the majority of Linux installations out there have it this way so we're fine.
(If you don't use modules: git grep MODULE_PARM_DESC -- drivers/gpu/drm/radeon/ )
You may have hit the same issue as I, see: http://thread.gmane.org/gmane.comp.video.dri.devel/78328
Reverting commit 2d6cc729 fixes the problem for me, setting radeon.no_wb=1 doesn't help.
