I'm having the exact same problem as described by pureblood. Also using HD3650 AGP.
It's not Kubuntu Jaunty specific as I experienced it on Ubuntu 9.04 Amd64 fresh install, Mythbuntu 9.04 Amd64 fresh install and Ubuntu 9.04 live CD. Each time, fglrx is not enabled.
Interestingly, this problem only appeared when I replaced my motherboard from Asus K8N (NVIDIA nForce3) to Gigabyte GA-K8VM800M Rev1.x (VIA K8M800). But it doesn't seem to be related to the mainboard since pureblood is on an intel configuration.

Option "DRI" "off" did indeed restore desktop display but it's more a workaround than a solution.
Option "AGPMode" "8" did not help, and unfortunately my BIOS does not let me change any AGP settings (except voltage which is on default).

The on board video is supposedly disabled by the BIOS in the presence of an AGP card, but I'm not sure if linux correctly ignores it or not always completely...

dmesg, xorg.conf, Xorg.0.log and lspci -vvnn generated with Mythbuntu are in the attachment.
