ati radeon dual-head hard system lockup

[Vladislav Grinchenko]

Hi,

I have upgrades my computer from FC4 (Xorg 6.8.2) to FC5 (Xorg 7.0.0)
and the upgrade broke my dual-head setup.

xorg-x11-server-Xorg-1.0.1-9
xorg-x11-drv-ati-6.5.7.3-4

I use 2 17" LCD monitors with ATI RV370 5B60 Radeon X300 PCIE card (both
CRT inputs) with MergedFB option. Everything works fine except that
I get hard system locks periodically. I noticed that right before the 
lockup Xorg grabs 100% of cpu.

Reading the mailing list, someone mentioned that 'ati-1-0-branch' has a
fix. Can somebody guide me through the process of extracting the branch
and building the drop-in module? (or RPM?). I tried to check the branch
out myself and build to no avail (following instructions on CVS
page[1]):

cvs -d :pserver:anoncvs at anoncvs.freedesktop.org:/cvs/xorg login
cvs -d :pserver:anoncvs at anoncvs.freedesktop.org:/cvs/xorg co -r 
     ati-1-0-branch -P app data doc driver font lib proto util xserver

This only gave me the driver:

$ cd driver/xf86-video-ati/
$ autogen.sh 
  ...
Makefile.am:24: BUILD_LINUXDOC does not appear in AM_CONDITIONAL
autoreconf: automake failed with exit status: 1

Any advice/guidance would be highly appreciated.
