I have found a solution. from http://redhat.secsup.org/fedora/core/updates/5/i386/ reinstall kernel-2.6.16-1.2133_FC5.i686.rpm kernel-devel-2.6.16-1.2133_FC5.i686.rpm kernel-doc-2.6.16-1.2133_FC5.noarch.rpm boot the old, well working kernel and reinstall fglrx module from ati ( ati-driver-installer-8.26.18-x86 ) fglrx and eth0 are still on one interrupt without any trouble at all.
