after upgrading xorg / error driver

[gustaaf wijnands]

Hello,

after portupgrading xorg to 6.8.1, X still works but there seems to be a 
problem with the drivers. It produces next error:

drm0: <ATI Radeon RS200 Mobility IGP 340M> port 0x9000-0x90ff mem 0xd0300
000-0xd030ffff,0xd8000000-0xdfffffff at device 5.0 on pci1
info: [drm] Initialized radeon 1.11.0 20020828 on minor 0
error: [drm:pid526:radeon_cp_init] *ERROR* radeon_cp_init called without 
lock he
ld
error: [drm:pid526:radeon_unlock] *ERROR* Process 526 using kernel context 0

In /var/log/Xorg.0.log I see

(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

Anyone a solution?
