Having established that's it's an SELinux issue using "setenforce 0",
you might find that this is a less drastic fix:

# semanage fcontext -a -f -- -t textrel_shlib_t \
	'/usr/lib(64)?/ati-fglrx/.*\.so(\..*)?'
# restorecon -Rv /usr/lib/ati-fglrx

After doing that, try "setenforce 1" and see if things still work. If
so, include the result of this test in your SELinux bug report.
