[radeonhd] flicker in dual monitor setup with X1600XT

Hi,
We've recently upgraded all the workstations in my department to nice new HP machines with X1600XT PCIe cards (RV530 chipset I think), dual 24" HP LP2465 monitors, and Fedora 8. So far they've worked great with the RadeonHD 1.1 drivers, until we went to an extended desktop and started using them full time. On all of our machines the right display (i.e. second display) has a weird flicker problem. Every few minutes horizontal black lines will randomly flash quickly across the screen, and maybe once an hour the screen completely looses its signal for about a second and then comes back on.
I've ruled out the monitors or the videocard/workstation at this point. Also, the fact that it happens on all the machines leads me to believe its a driver issue not faulty hardware. Using the same monitors and RadeonHD release on my X1650 AGP in an older workstation never exhibited the problem once. I'm guessing it's this particular chipset or maybe the fact that it's dual DVI out. The AGP card without the problem is VGA/DVI.
The issue is always in the secondary port. From xrandr:
DVI-I_2/digital connected 1920x1200+1920+0 519mm x 324mm
1920x1200 60.0*+
I'd love to help trace this issue if no one has experience the problem before. I searched through the archives and haven't found anything similar yet, so I'm guessing this is new. Please let me know if there is anything we can do to fix this because it's very frustrating and I love using the RadeonHD's.
If more info is required, please ask away.
Thanks,
-Dave
