these are the versions I have running, I think are the latest, and will work:

why did you do this step? If possible, since you compiled them from scratch, 
you can remove the packaged versions.

looks correct, basically they're included with the kernel, so you should be 
fine here.

Did you ever look into why it would stop working after two weeks?

but previously, it was working fine when it did work?

Well, it should be possible to get it working with your VIA firewire since it 
did work before. I would be curious though, if moving to a non VIA firewire 
chipset solves the 2week or any other issues you may have had?
