That's what I thought.

From Xorg.0.log:

(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 0xf805b000 at 0xb76dd000
(II) RADEON(0): [drm] Closed DRM master.
(II) RADEON(0): RADEONRestoreMemMapRegisters() :
(II) RADEON(0):   MC_FB_LOCATION   : 0xfffff000 0xfffff000
(II) RADEON(0):   MC_AGP_LOCATION  : 0xffffffc0
(==) RADEON(0): Backing store disabled
(WW) RADEON(0): Direct rendering disabled

However, /etc/conf.d/modules:
modules="agpgart drm radeon fuse"
