irq priority for firewire device

would it be possible to make something like "rtirq" working in a full
preempt and noticks-disabled vanilla kernel without rt-patching?
As far as I can see adjusting IRQ priorities seems to be essential for
firewire-audio as long as firewire's IRQ-priority is subordinated at the
low end by default, and if this could be changed in a user friendly way
I'd see no more need for rt-patching kernels.
I compared all kernel mods for audio live performance and recording in
practice, and the only feature I really miss in non-rt-kernels is this
rtirq thing. But I'm no coder and need guiding hands for understanding
deeper kernel and os matters, so please bear with me if this idea should
be foolish, misplaced or redundant/obsolete.
Best regards Gerhard
