No they are not. It's a supplementary driver only.
By -rt kernel, I refer to the patch set maintained by Thomas Gleixner and
Ingo Molnar:
http://rt.wiki.kernel.org
http://www.kernel.org/pub/linux/kernel/projects/rt/
The patch set is progressively integrated in Linus's tree but there's
still some work left and it will likely continue to exist for a long time.
FWIW LWN has articles about its (progressive) integration.
Of course, if we add a -rt flavor, we should have someone willing to
maintain it within the kernel team.
Cheers,
