Description Lennard 2009-12-26 02:59:45 UTC
Everytime I start X, drm gets disabled, here is a snippet from /var/log/Xorg.0.log:

(II) RADEON(0): [drm] installed DRM signal handler
(WW) RADEON(0): [agp] AGP not available
(EE) RADEON(0): [agp] AGP failed to initialize. Disabling the DRI.
(II) RADEON(0): [agp] You may want to make sure the agpgart kernel module
is loaded before the radeon kernel module.
(II) RADEON(0): [drm] removed 1 reserved context for kernel
(II) RADEON(0): [drm] unmapping 8192 bytes of SAREA 0xf802e000 at 0xb7183000
(II) RADEON(0): [drm] Closed DRM master.
(II) RADEON(0): RADEONRestoreMemMapRegisters() :
(II) RADEON(0):   MC_FB_LOCATION   : 0xe7ffe000 0x1fff0000
(II) RADEON(0):   MC_AGP_LOCATION  : 0xffffffc0
(==) RADEON(0): Backing store disabled
(WW) RADEON(0): Direct rendering disabled

I am on gentoo-sources 2.6.31-r6 with xf86-video-ati-6.12.4 and xorg-server-1.6.5-r1.

I have entered the appropriate kernel modules in a correct order in /etc/modules.autoload.d/kernel-2.6, to no avail. Manually removing and reloading modules does not work either.

It's a kernel issue, the X driver can't do anything about it.

If it's a newer card with a PCIe based GPU,

    Option "BusType" "PCIE"

may be a feasible workaround.
