Current state of firewire support?

[Quartz]

 From what I understand, FreeBSD "dropped support" for firewire at some 
point in the past couple years, but I'm having trouble finding detailed 
information on what exactly changed. Assuming 10.1-release, is there any 
easy way to get an old firewire drive mounted? Is there a config file 
that will load something at boot? A package I can install? Do I have to 
patch the kernel? Or is firewire just totally gone for good?
