Loading the drm/radeon kernel modules with debug=1 might produce some 
additional data if you can reproduce the problem. I haven't filed any 
bugs on the matter, but I have talked to one of the driver developers. 
For me, this problem was rapid lockups of X when running gnome-terminal 
and Firefox. I got it on both my Radeons, an 8500 and a 9600 Pro.

Don't think the radeon driver does dual-link yet, although I could be 
wrong. With single link, you can do about 1900x1200 on a 
reduced-blanking mode. These modes were designed for LCDs so they should 
be fine on one.

It's called reduced blanking because CRTs used to require the vertical 
blanking time to aim the gun back up to the top left of the monitor from 
the bottom right, but LCDs no longer require that.

Thanks,
Donnie
