A black thin line moving across my screen

Recently, I switched to arch linux, after having problems with evo/lution.

I wanted to know if there's anything more I can do to optimize my graphics chip.
I started noticing a thin black horizontal line moving up and down my screen at random times. It's quite annoying.
I recently installed the xf86-video-ati driver on my laptop.
Here are my video cards properties.

> lspci -v
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV515/M54 [Mobility Radeon X1400] (prog-if 00 [VGA controller])
        Subsystem: Lenovo Thinkpad T60 model 2007
        Flags: bus master, fast devsel, latency 0, IRQ 16
        Memory at d8000000 (32-bit, prefetchable) [size=128M]
        I/O ports at 2000 [size=256]
        Memory at ee100000 (32-bit, non-prefetchable) [size=64K]
        [virtual] Expansion ROM at ee120000 [disabled] [size=128K]
        Capabilities: <access denied>
        Kernel driver in use: radeon
        Kernel modules: radeon

My graphics chip's config settings

> cat /etc/X11/xorg.conf.d/20-radeon.conf

Section "Device"
        Identifier  "Mobility X1400"
        Driver  "Radeon"
        Option  "SWcursor"              "off" #software cursor might be necessary on some rare occasions, hence set off by default
        Option  "EnablePageFlip"        "on"  #supported on all R/RV/RS4xx and older hardware, and set on by default
        Option  "RenderAccel"           "on"  #enabled by default on all radeon hardware
        Option  "ColorTiling"           "off"  #enabled by default on RV300 and later radeon cards
        Option  "EXAVSync"              "off" #default is off, otherwise on. Only works if EXA activated
        Option  "EXAPixmaps"            "on"  #when on icreases 2D performance, but may also cause artifacts on some old cards. Only works if EXA activated
        Option  "AccelDFS"              "on"  #default is off, read the radeon manpage for more information
EndSection

It sounds like you are describing an artefact to me -- does it go away if you disable this option?

It started before I added the 20-radeon.conf, if it happens again I will disable this option.
