I just bought a Compaq V2000 laptop and I'm working with Debian's unstable branch, which now proudly boasts X.org. The video adaptor is a Radeon XPRESS 2.
It's got a wide screen (I think 1280x768) which seems to work fine under the old vesa driver. The problem happens when I change to the "radeon" driver or "ati". Under both drivers, gdm loads fine, but when I log in and KDE starts up, the shit hits the fan.
If I switch out to a console right-fast, nothing will go wrong until I head back to my X session, which will invariably crash the system. I can't even SSH in to reboot it! And yes, if I don't leave the X session as KDE starts up, it crashes as well.
I'm attaching my xorg.conf and "lspci"
