Problems with Xorg restarting after KDE logout

[Martin Marques]

I've experienced problems with logouts (any user) on my FC6. Basically, 
X crashes and I end up in a terminal. From there I can start X again 
without a problem but on logout I don't get the kdm login screen.

Looking at the logs I found something very peculiar:

When starting X and kdm ffom boot I see this in the Xorg.0.log:

(II) SAVAGE(0): [drm] bpp: 32 depth: 24
(II) SAVAGE(0): [drm] Sarea 2200+284: 2484

(II) SAVAGE(0): [agp] Mode 0x1f000201 [AGP 0x1106/0x3116; Card 
0x5333/0x8d04]

But when I logout and X has to restart I get this:

(II) SAVAGE(0): [drm] bpp: 32 depth: 24
(II) SAVAGE(0): [drm] Sarea 2200+284: 2484
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 6, (OK)
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 6, (OK)
drmOpenByBusid: Searching for BusID pci:0000:01:00.0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 6, (OK)
drmOpenByBusid: drmOpenMinor returns 6
drmOpenByBusid: drmGetBusid reports pci:0000:01:00.0
(II) SAVAGE(0): [drm] DRM interface version 1.0
(II) SAVAGE(0): [drm] drmSetBusid failed (6, pci:0000:01:00.0), 
Permission denied
(EE) SAVAGE(0): [drm] DRIScreenInit failed.  Disabling DRI.
(EE) SAVAGE(0): DRI isn't enabled

Now, two things come up from here:

1) In the first boot it's using version 1.3 of DRM interface, while at 
restart it uses 1.0. What can be wrong?
2) There seems to be a permission error when trying to access the SAVAGE 
card at the busid specified.

Any clues?
