patch

It seems that current xf86-video-radeon doesn't automatically load the kernel
module anymore. This probably happened during the addition of KMS support,
which caused drmOpen() call to stop doing this task. More details on that in:

https://bugs.freedesktop.org/show_bug.cgi?id=72849

AFAIK this isn't a big problem on GNU/Linux, because on that platform you
expect the kernel module to be loaded much earlier anyway. However on other
platforms (such as GNU/kFreeBSD and probably FreeBSD as well), X is expected to
load the modules it needs (i.e. noone else will do it for her).

I'm attaching a patch that restores the intended behaviour, however using
fallback method like the intel driver does (i.e. if
drmCheckModesettingSupported() fails, then try load the module, and then try
drmCheckModesettingSupported() again).
