I have a similar card (also the xpress 200m), I will try to reproduce
this bug. However, Rodrigo's Xorg0.log shows all these warnings and
errors.
(WW) RADEON(0): Direct rendering disabled
(II) RADEON(0): XAA Render acceleration unsupported on Radeon
9500/9700 and newer. Please use EXA instead.
(II) RADEON(0): Render acceleration disabled
[355167.718141] [drm] Loading R300 Microcode
[355167.818662] [drm:radeon_do_init_cp] *ERROR* Failed to load firmware!
Perhaps these need to be addressed to fix your other issue. Please
install libdrm-radeon1, firmaware-linux, firmware-linux-nonfree. Also
use EXA in your xorg.conf
For example:
Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
EndSection
Section "Device"
Identifier "ATI Radeon Xpress 200M"
Driver "radeon"
BusID "PCI:1:5:0"
Option "AccelMethod" "EXA"
Option "AccelDFS" "1"
Option "EnablePageFlip" "1"
Option "Monitor-LVDS" "Internal Monitor"
EndSection
Section "Monitor"
Identifier "Internal Monitor"
EndSection
Section "Screen"
Identifier "Default Screen"
Device "ATI Radeon Xpress 200M"
Monitor "Internal Monitor"
DefaultDepth 24
SubSection "Display"

Please report back!
