Well Linus seemed to like it when he spoke in Berlin last year, I guess
number one would be getting an answer from the authors if possible (and give
the poor folk some time) and generating a clean patch to 2.1.x for it.

I suspect fixing that isnt hard. RT-Linux plays some IRQ queueing games ,
and from the SMP kernel point of view the patches I produced that don't
go into the standard 2.0.x kernel are basically doing the same thing but
in the kernel instead of in the RT layer.
