For anyone who followed this, I successfully recompiled a Fedora kernel
with the old school firewire stack enabled. Then I copied those modules
over to the real Fedora kernel rather than booting my newly built one.
There is probably a simpler way to compile _just_ the ieee1394 modules,
but Fedora's docs were hard to follow, and I could not find simple
instructions on how to build just a few internal modules.
These (http://forums.fedoraforum.org/showpost.php?p=769367&postcount=40)
were the best instructions I found on rebuilding a fedora kernel. In
make menuconfig I enabled the old ieee1394 stuff and left the new stuff
in there. Then once the kernel was built I copied
~/rpmbuild/BUILD/kernel-2.6.21/linux-2.6.21.i686/drivers/ieee1394/*ko to
/lib/modules/2.6.21-1.3228.fc7/kernel/drivers/ieee1394. Then I added the
new fw_core and fw_ohci to /etc/modprobe.d/blacklist and reboot. Upon
reboot the old school firewire modules were loaded and plugreport showed
my SA3250HD just like it used to.
This is not an elegant solution, but its got me working for now, I'll
have to exclude future kernel updates unless I want to keep doing this.
Oh well I'm happy for now.
Some other links that may be of help.
