Dave Airlie wasn't impressed by the change. The reply cited below:

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
on some other arches.

So if a distro isn't shipping a compatible userspace, I'd rather they didn't
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.

What should we do? The patch itself is trivial, so no hard work to maintain
(mostly just for 2.6.31, though).

Alternatively, we can disable modeset option in /etc/modprobe.d/*.

OTOH, if the standard user-space stuff on 11.2 doesn't support KMS, it's
actually safer to remove the feature from the kernel, as Dave suggested in the
