The speed of updates wasn't the original question, it was where to get
the right stable or development DRM modules.

If people decided to upgrade their kernel, they'd already get a later DRM
that should function with the latest XFree86 4.2.x release regardless of
whether the DRI trunk DRM modules have anything to do with it. Thus getting
whatever bug fixes are in the later kernel.

Forget the DRI trunk for a second, what does 2.4.20 do with XFree86 4.2.x ?
That should be stable. As for your question, have you posted more details
on the problem ?

Linus should submit it here for inclusion - simple. I doubt any of us
are tracking 2.5.x that closely at the moment.
