I'm sort of torn on this, when radeon KMS moves out of staging it will
be disabled by
default using the current option. It will build everything always and
disable/enable like this patch
does. I'm not willing to do that yet esp now in -rcX time as it might
break builds
on some other arches.

So if a distro isn't shipping a compatible userspace, I'd rather they
didn't ship
the kernel support built at all until we move it from staging.

AFAIK you guys don't use -ati on a lot of cards kms is useful so I'm
not sure when you'll
ever have a compatible userspace.

Dave.
