Be patient, this stuff is very new and vendors are rightfully
conservative.  They are probably just waiting for the development to
settle down a bit before committing resources to supporting the RT
kernel.

Once some distros start to offer the RT kernel as an option I would
expect a lot of interest from hardware vendors as it really allows the
hardware pushed to its limits.  For example pro audio interfaces are
heavily marketed based on the lowest achievable latency, this will let
them put better numbers on the box, and will probably improve Linux
support a lot, because the marketing will have to be "FooAudio5000, now
featuring 0.6 ms*** usable latency (***Linux RT kernel required, 2.6 ms
under Windows/MacOS)" :-).
