I am wondering myselves too.
The new module parameter "remote_dma" (default = N, enable
unfiltered remote DMA = Y) replaces the former build-time
option CONFIG_FIREWIRE_OHCI_REMOTE_DMA. (This kernel
configuration option was located in the "Kernel hacking"
menu, item "Remote debugging over FireWire with firewire-
ohci".) It is therefore now possible to switch on RDMA at
runtime on all kernels with firewire-ohci loaded or built-in,
for example for remote debugging, without the need for a
custom build option.

I am not an expert in these matters, but could it be that OP is wrong with regarding to firewire? From what I am reading here is that dma is off by default, and can only be activated at runtime.
If the OP is right about the need to disable firewire, I hope someone could explain why so…
