Good news. I installed:
http://download.fedora.redhat.com/pub/fedora/linux/core/updates/testing/5/i386/xorg-x11-drv-ati-6.5.8.0-1.i386.rpm
removed my /etc/X11/xorg.conf and ran
system-config-display --reconfig
and I was up and running again. The T30 built-in LCD does 1024x768 natively,
but the xorg.conf file it wrote only supported 800x600, but that's an easy
thing to fix by hand.
Note that I haven't tried to tweak the AGP speed or turn on acceleration or
anything like that, yet.
Following the advice described below didn't work for me at all.
