For 2.5, there probably is no intention of keeping that around.  But can
we honestly ditch it in the middle of a stable kernel?  Personally I
don't use it, but its not polite ...

Linus ditched drm 4.0 months ago.  It only survives in arch add on
patches like ia64 and in -ac trees.

I know.  I meant we should continue to support the drm-4.0 package. 
It's the usual song ... we shouldn't change interfaces or required tools
in a stable series, and the least we can do is make 4.0 available
somehow, because someone may rely on it.

On the flip side, I don't care, and I suspect the people who actually
are using DRM are on 4.1 now.  Further, if _you_ are maintaining the
cruft and it bothers _you_, then stop :)

No, it also survives as an add-on tarball for the standard kernel:
http://www.kernel.org/pub/linux/kernel/v2.4/drm-4.0.x.tar.bz2

Let me dig through my old mail so I can quote Linus on this... Here's
what he said in his Linux 2.4.8 announcement message (Subject
"Linux-2.4.8", sent on August 10th of this year):

The impression I get (for 2.4) is that DRM 4.1 comes standard but you
should still be able to use 4.0 if you want, via that tarball.

I said it shouldn't have been ditched, Linus overruled.

That argument doesnt fly. The 4.0 DRM is the only working GMX renderer..

So what DRM can build out of tree easily - e.g. the Caldera LTP
(3.1 early access) had a DRM package built completly out of tree.

David, would you remove drm-4.0 from the ia64 patch if I'd do the work
again and package an up-to-date and ia64-capable drm 4.0 out-of-tree?

XFree86 4.0, 4.1, ... ship with the DRM kernel modules buildable from
the XFree86 tree too

Been there, done that.

Having seen the XFree build process this doesn't look like an option to
me anymore.  Also a separate tarball easyfies building a new set of modules
for a new kernel a lot.

In my opinion it's extremely bad style to remove drm-4.0 from the 2.4
kernel (remember, it's supposed to be a *stable* kernel series).  As
far as I know, there are binary-only drivers out there that work only
with drm-4.0.  I don't think it's fair to break someones working setup
just because of a kernel upgrade.

But if there is a good reason to remove it, I'm certainly willing to
listen.  My understanding is that for Keith it's good enough if
drm-4.0 goes away in 2.5.

Agreed.  Stil I don't think specific ports should fix that up - this
will sooner or later leed to a full fork.

_Any_ kernel update may break binary drivers.

My opinion is that including the drm changes in the ia64 patch just makes
the diff to handle much bigger.

Marcelo, are you willing to put in drm 4.0 as option in 2.4.18 again?

Why would I ? 

What is wrong with the current drm version ?

That you need to have XFree 4.1 installed, if you have XFree4.0, then
you can't have drm :(

Yes, that drm is incompatible sucks :(
