You can probably achieve this by creating a pair of local udev rules in
/etc/udev/rules.d/10-custom.rules that identify your specific devices
and create the device nodes before the "standard" Fedora rules get a
chance to do it.
See: http://www.reactivated.net/udevrules.php for details on how to
write these rules.
