Problem with an ATI x2900 video adapter

[Michael D. Norwick]

Good Day;

I am in the final steps of completing a fresh installation of FreeBSD 
8.2 on a workstation with a DFI LanParty motherboard, AMD Athlon 64 
processor, 3 GB of ram, an ATI Radeon x2900 graphics card, and root on 
ZFS filesystem.  Using ports.tar.gz downloaded, and src CVSup'd this 
morning, gnome2 is still compiling and installing.  While I did have 
some minor issues with the build of some dependencies, it was nothing I 
could not work through.  I was surprised this afternoon when, while the 
installation of gnome2 was working, I think it was building GCC 4.4 and 
friends, the HP 2010i LCD monitor I use on the machine appeared to lose 
the input to its DVI port.  The HD activity light was still flickering 
so I let it continue and waited a hour or so for it to quit indicating 
activity before I pressed the reset button.  The PC restarted and no 
filesystem errors were apparent on restart.
I would like to know if anyone else has experienced this or, if a PR is 
necessary against the Xorg radeon driver.
The ATI Catalyst utility needs windows or linux and I have neither.
There is nothing of value in dmesg or Xorg.0.log

Thank You,

PS;  Many thanks to the maintainer of the mfsBSD zfsinstall .iso.  It 
worked flawlessly for setting up this system.
