I can't help you on the Radeon drivers since I don't have one. Does ATI have a forum like the one nVidia has? I assume you've already tried to install the latest RPM from them. I assume the ATI RPM comes with both X drivers and kernel drivers. If it's the X driver that is causing the problem you could downgrade to the version of X that comes with Red Hat 9 (ick). If it's the kernel then you could downgrade to an older kernel (ick). Best thing would be to hound ATI for drivers that work with Fedora (if they aren't already out there).
As far as the apt-get thing goes:
