Black screen when using DRI with radeon(4)

[Mark Rosenstand]

Hello list,

If I enable DRI, my monitor blacks out when starting X. It doesn't go
into stand-by or anything, it just shows a black screen.

I'm using a Radeon 7000 in a K8T800-based motherboard. The problem
exitst in 6.8.2, 6.8.99.900 snapshot and CVS from a couple of hours ago.

The machine is running Linux 2.6.13 and the monitor doesn't support DCC.

I've tried:
  - to compile agpgart, amd64_agp, drm and radeon as modules.
  - to disable all Option's for radeon(4).

The logs doesn't mention a thing. Here's the diff:
