fglrx(0): [drm] failed to remove DRM signal handler

[Zibi1981]

I'm trying to make my Radeon X800Pro work on Arch Linux with X.Org X servers version 1.4.0.90-6. I installed newest ATI Catalyst drivers available in Arch's repository (v. 8.01-1) and after that did

aticonfig --initial --input=/etc/X11/xorg.conf

Unfortunately when I try to run a test with

X -config /etc/X11/xorg.conf

I can only see and move my mouse cursor, but that's all, and after I quit server with Ctrl-Alt-Backspace there is an error displayed at the end of the console output

(II) fglrx(0): Shutdown CMMQS
(EE) fglrx(0): [drm] failed to remove DRM signal handler
(II) fglrx(0): [drm] removed 1 reserved context for kernel
(II) fglrx(0): [drm] unmapping 8192 bytes of SAREA 0x2000 at 0xb7737000
(II) fglrx(0): [drm] Closed DRM master.

Anyone could help me with this?
