It never worked :) Just found out about. I run fbsd inside a vm fusion
instance on os-x.
From the vmware fusion faq:
----
Can I use my FireWire camera or printer in Windows?
No, VMware Fusion does not support virtualizing FireWire devices,
so you cannot use your FireWire camera or printer with Windows. If your
FireWire printer has Mac drivers, you can use it via printer sharing or
VMware Fusion’s driverless printing feature. Also, you can access your
FireWire hard drives in VMware Fusion by mapping the hard drive to a
VMware Shared Folder. Alternatively, if your device has both a USB and
FireWire connections, you can connect the device to your virtual machine
as a USB device instead.
----
The iMac DV (ppc based) does no longer boot with firewire built in,
since r187993. Right now it does not boot at all. It is a bit a flacky
machine. But this is not an urgent issue. I have some other problems
with it.

I did, but it needed a bit of tuning :)
Here is what I have now. The above patch I backed out. The only diff I
use is this:
Index: fwohci.c

reg = fwphy_rddata(sc, FW_PHY_SPD_REG);
The 6000 is the smallest value which works. 5500 does not work. Between
I did not play.
Thanks a lot!
Can I test something else?
