X server log

I'm using GIT commit c5d62fa0e8f52c3264ff9db3ff10cdf5a806bfc0 on a Lenovo T60
with Fedora 9 Beta. Since about two weeks I noticed that at some point in time
font glyphs are randomly drawn incorrectly, e.g. all "u" glyphs might be drawn
as "3"'s. It usually gets worse over time, ie. the texts become more and more
unreadable. But sometimes (opening a new window???) it also improves again.


SW version information:
xorg-x11-server-Xorg-1.4.99.901-22.20080415.fc9.i386
cairo-1.6.4-1.fc9.i386


This is the chipset the X server detects:

(--) PCI:*(0 at 1:0:0) ATI Technologies Inc M52 [Mobility Radeon X1300] rev 0,
Mem@ 0xd8000000/0, 0xee100000/0, I/O @ 0x00002000/0

$ /sbin/lspci | fgrep 01:00

Device section from xorg.log:

Section "Device"
        Identifier  "Videocard0"
        Driver      "radeon"
        Option      "AccelMethod" "EXA"
        Option      "DisplayPriority" "BIOS"
        Option      "DynamicClocks" "On"
EndSection

I've attached Xorg.0.log.
