In a nutshell, no. Support for redhat 9 finished a while back, and i doubt you could get those updates unless you downloaded each updated rpm by hand and installed them.
Can you not recompile your kernel to include support for firewire?
I just found this link that says firewire is broken on fedora, suffering possibily a similar stack problem to certain other drivers. The link is below:
It may be possible to work around it with a little effort, and by compiling/using the latest cvs subversion code from here, and reconfiguring your kernel to use 8k stacks as opposed to 4k..
