Can't run X anymore -- missing kernelmode setting

[Jan Danielsson <jan.m.danielsson%gmail.com@localhost>]

Hello,

   I just upgraded my packages (using pkgsrc HEAD), and now I can no
longer run X. When I try to start it, it says that I can't use DRM
because my kernel is missing KMS.

   Is there an easy fix for this? Some magic option for some X package?
Or do I need to go back to an older pkgsrc?

   I'm using the radeon-driver, in case it matters.
